fix(imx8ulp): fix suspend/resume issue when DBD owner is s400 only

After resume from APD power down, XRDC is initialized by S400 but
the PAC2 and MSC0-2 are not configured, so only DBD owner can access
the resources.

We have to move GPIO restore after TFA XRDC reinit and configure
PDAC for PCC5 before enabling eDMA2 MP clock

feat(imx8ulp): update the upower config for power optimization

Enable the AFBB by default for active mode when APD side wakeup
from low power mode to align with the first time boot up.

Update the power mode configs to force shutdown all the
necessary power switches to optimize the power consumption.

To reduce the pad power consumption, put all the pad into
OFF mode to save more power. the PTD's compensation should
also be disabled in low power mode to save more power.

when APD enters PD mode, the LDO1(used by DDR) can be shutdown
to save power. when APD enters DPD mode, the BUCK3(supply for
APD/LPAV) can be shutdown to save power.

In single boot mode, When APD enters DPD mode, buck3 will
shutdown, LDO1 should be off to save more power as the DDR
controller has lost power.

In dualboot mode, the LPAV is owned by RTD side. When APD enters
low power mode, APD side should not config those PMIC regulators
that used by the resource owned by RTD side.

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.
