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

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 the DDR frequency scaling support on i.MX8ULP.
Normally, the freq_index define is as below:
0: boot frequency;
1: low frequency(PLL bypassed);
2. high frequency(PLL ON).
Currently, DDR DFS only do frequency switching between
Low freq and high freq.

feat(imx8ulp): add APD power down mode(PD) support in system suspend
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.

feat(imx8ulp): add the basic support for idle & system suspned
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.
