the mmap region num is not enough for the mmap regions,
so increase it, increase the xlat_table num too.

below commit mapped 16 MB memory from the start of DRAM(0x80000000),
which may have conflict with the shared memory used by Trusty OS:
LF-8819: plat: imx8ulp: ddrc switch auto low power and software interface
change the mapped memory to 'vdev0buffer' reserved memory (0x8ff00000)
to avoid memory conflict. This commit also bumps the XTLB tables
to avoid mapping failure.

Enable switch between DDRC Auto low power and software/hardware
control modes DDRC Auto low-power mode is used when system is
active, software/hardware control mode is used when going into
suspend. Enable switching between Auto mode and SW/HW mode in
enter/exit retention routines.
Set LPI_SRPD_LONG_MCCLK_GATE_WAKEUP_F2 Max setting to allow
LPDDR_EN_CLKGATE reload LPI_SRPD_LONG_MCCLK_GATE_WAKEUP_F2 to
exit retention mode

The APD can be put into PD mode when linux suspend(mem). This patch
add the support for it. As the whole AP domain's context will be lost,
so we must save the necessary HW module states before entering PD mode,
and we need to restore those contexts when system wake up. Fot details
about which HW module's state will be lost, please refer to the RM.
When APD enter PD mode, only the wakeup event connected to the WUU
can wakeup APD successfully. The upower wakeup source is used to
wakeup APD by RTD due to the factor that the MU between A core & M
core is not connected into WUU to generate wakeup event.
as the SRAM0 will be power down when APD enters PD mode, so we
need to re-init the scmi channels(resides in the SRAM0). otherwise
the SCMI can NOT work anymore.

Add basic support for the cpuidle(cluster retention) and system
suspend support using the HW sleep mode.
When system enter low power mode after doing reboot twice, APD
will be failed to exit from low power mode successfully. it is
because that after secondary reboot, upower will modify the default
power switch config, then DDR will be off wrongly. So config the
low power mode info explicitly before APD entering any low power
mode.

Add the basic support for i.MX8ULP.
The i.MX 8ULP family of processors features NXP’s advanced
implementation of the dual Arm Cortex-A35 cores alongside
an Arm Cortex-M33. This combined architecture enables the
device to run a rich operating system (such as Linux) on
the Cortex-A35 core and an RTOS (such as FreeRTOS) on the
Cortex-M33 core. It also includes a Cadence Tensilica Fusion
DSP for low-power audio and a HiFi4 DSP for advanced audio
and machine learning applications.
