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.
