configs: j721e_evm_a72: Disable UHS mode 

The J721E PM1 SoM board uses a TPS65917 PMIC with the MMC card IO
supply provided by LDO1 regulator. This regulator comes up in bypass
mode by default with the input supply at 3.3V. As such, the board
fails to boot with UHS mode enabled.

This can probably work if the regulator is switched into regular
operating mode, but there is no support for this PMIC in U-Boot.
So disable the UHS mode to have the boot functional on this board.
