MLK-17346 board: imx8mq: Change the SW3A standby mode to off

On i.MX8MQ EVK board, the SW3A is used for VDD_DRAM supply,
when system enter DSM mode, the DDR is put into retention mode,
the VDD_DRAM supply can be power off to reduce the leakage
current to save power. Set the SW3A mode to APM_OFF mode to power
off the SW3A when PMIC enters standby mode.
