NXP S32G2/S32G3 SoC based platforms do not
use a pin for SD-Card write protection used by
the uSDHC controller.
Hence, adding 'disable-wp' usdhc device-tree property in order to fix
observed warnings on SD boot as the following:
"host does not support reading read-only switch, assuming write-enable"
