To be able to use RSE comms without MHU, a first step is to disentangle
the rse_comms.c file with MHU code direct calls. This is done with the
creation of a new file rse_comms_mhu.c. New APIs are created to
initialize the mailbox, get max message size and send and receive data.

feat(cpus): add sysreg_bit_toggle
Newer cores in upcoming platforms may refuse to power down. The PSCI
library is already prepared for this so convert platform code to also
allow this. This is simple - drop the `wfi` + panic and let common code
deal with the fallout. The end result will be the same (sans the
message) except the platform will have fewer responsibilities. The only
exception is for cores being signalled to power off gracefully ahead of
system reset. That path must also be terminal so replace the end with
the same psci_pwrdown_cpu_end() to behave the same as the generic
implementation. It will handle wakeups and panic, hoping that the system
gets reset from under it. The dmb is upgraded to a dsb so no functional
change.

This patch adds support for Local Chip Addressing (LCA). In a multi-chip
system, enablig LCA allows each GIC Distributor to maintain its own
version of routing table. This feature is activated when the
GICD_CFGID.LCA bit is set to 1.
The existing `gic600_multichip_data` data structure did not account for
the LCA feature. To support LCA:
- `rt_owner_base` is replaced by `base_addrs[]`. This is required
because each GICD in the system needs to be configured independently,
and their base addresses must be passed to the driver.
- `chip_addrs` is changed from 1D to 2D array to store the routing table
for each chip's GICD. The entries in `chip_addrs` are configuration
dependent, as the GIC specification does not enforce this.
On a multi-chip platform with chip count N where LCA is enabled by
default, the `gic600_multichip_data` structure should contain all copies
of the routing table (N*N entries). On platforms where LCA is not
supported, only the first sub-array with N entries is required. The
function signature of `gic600_multichip_init` remains unchanged, but if
the LCA feature is enabled, the driver will expect the routing table
configuration in the described format.

Update preloaded_bl33_base for legacy product for Yocto.
The Yocto Jenkins build was initially configured to build products
where the starting of the DDR is from 0x0000 0000. And if there is
no NS_image_offset set, the Jenkins is not able to acquire the correct
address offset to boot up the system. However, in the direct OS boot,
there is no issue as the user shall always include the address offset
during the compilation phase. Otherwise, the code shall execute the
default address offset. Besides that, this also provides the
flexibility to user to customize their SoC design by not restricted
to the default address.
SDMMC block size. It was changed due to the need when boot to Linux.
Kernel.itb size is big thus we have to increase the available reading
block size. Otherwise for normal U-boot and Zephyr it shall not be
reading a big block size to avoid "garbage" data.

Disabling AXI port, enabling host interface and both enabling/disabling
software self-refresh services are already present inside the driver
source code.
Factorize by gathering them as services inside the generic part,
and adapt driver to call these new functions.
Add services to manage quasi-dynamic registers. DDRCTRL contains
quasi-dynamic registers, which are dynamic only under some conditions
defined by the user guide (with 4 groups).
In our driver, out of reset state, only groups 3 and 4 are updated.
Group 4 needs only sw_done/sw_done_ack sequence, already available.
Group 3 sequence include more conditions, that are gathered in
specific services. stm32mp_ddr_disable_host_interface() has been added
to do this.
Add dedicated generic service to toggle rfshctl3.refresh_update_level
and wait for completion.
Manage AXI ports and HIF when updating QD3 registers. Quasi-dynamic
group 3 (QD3) registers are updated when DDR is not completely
initialized, i.e. when AXI ports are not enabled and possibly when
host interface (HIF) is not enabled too.
In that case, a specific mechanism is necessary to restore the same
conditions as before accessing QD3 registers.
Static functions have been added to get AXI ports and HIF states and
are used to determine the needed conditions to set/unset.

The S32CC-based SoCs are organized in partitions. These are
software-resettable domains in which configuration participates in
MC_CGM, MC_ME, and RDC modules. A partition is an island that may
contain multiple blocks, each of which corresponds to a peripheral or a
core and can, in most cases, be reset individually. This reset structure
results in better device availability. If a fault is detected in a
software reset domain, that domain can be reset separately without
impacting the operation of the rest of the chip.

Peripheral PLL is one of the platform's PLLs, providing a clock for
peripherals such as UART, QSPI, uSDHC, SPI and CAN. Its source can be
either the FIRC or FXOSC oscillators. It has eight outputs (PHIs) and
their frequencies can be controlled programmatically using output
dividers. An additional output clocks the PERIPH DFS using the VCO
frequency of the PERIPH PLL.
