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.

This patch will enable vcore dvfsrc.
- VCORE DVFS is the feature to change VCORE/DDR Freq for power saving
- When there are no requests for using Vcore/DRAM, Vcore DVFS will
- lower the voltage and frequency of Vcore/DRAM to achieve power saving.

Now that all errata flags are all conveniently in a single list we can
make sweeping decisions about their values. The first use-case is to
enable all errata in TF-A. This is useful for CI runs where it is
impractical to list every single one. This should help with the long
standing issue of errata not being built or tested.
Also add missing CPUs with errata to `ENABLE_ERRATA_ALL` to enable all
errata builds in CI.

In FFH mode, When handling nested serrors, serror is handled once and
all subsequent serrors are considered handled.And EL3 directly return
to lower EL.
While returning to lower EL, x30 is restore to CTX_SAVED_GPREG_LR
address.CTX_SAVED_GPREG_LR address belongs to EL3 address range and
this address will not be accessible in lower EL.
After return to lower EL, when lower EL access x30, segmentation fault
happens and Kernel kills application.
This patch restore x30 to lower EL address (CTX_GPREG_LR) to avoid
segmentation fault at lower EL.

The model has a bug where it will not clear CPUPWRCTLR_EL1 on reset,
even though the actual cores do. The write of 1 to the bit itself
triggers the powerdown sequnece, regardless of the value before the
write. As such, the bug does not impact functionality but it does throw
off software reading it.
Clear the bit on Travis and Gelas as they are the only ones to require
reading it back.

ARM_SPMC_MANIFEST_BASE defines the base address of the SPMC manifest
used by BL32. In the non-RESET_TO_BL31 case, it is defined relative to
the top of Trusted SRAM. However, for RESET_TO_BL31, the
PLAT_ARM_SPMC_MANIFEST_BASE macro can be used to set it to a different
location which is then used to populate ARM_SPMC_MANIFEST_BASE.
As the RD-V3 platform and its variants have a different SRAM layout
compared to that defined in arm_def.h, define the
PLAT_ARM_SPMC_MANIFEST_BASE macro to an address suitable for this
platform and its variants.

In RESET_TO_BL31, the SPMC manifest base address that is utilized by
bl32_image_ep_info has to be statically defined as DT is not available.
Common arm code sets this to the top of SRAM using macros but it can be
different for some platforms. Hence, introduce the macro
PLAT_ARM_SPMC_MANIFEST_BASE that could be re-defined by platform as per
their use-case. Platforms that utilize arm_def.h would use the existing
value from arm common code.
