MLK-22851-3 imx8mq: Enable eMMC HS400 and SD UHS mode on EVK

iMX8MQ EVK board has a eMMC5.0 chip and supports SD3.0, so enable the UHS
and HS400 configs to enhance the eMMC/SD access.

The change also needs to set usdhc clock to 400Mhz, and add the off-on-delay-us
to SD reset pin, otherwise some SD cards will fail to select UHS mode in
re-initialization.
