feat(imx8ulp): ddrc switch auto low power and software interface
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
