mmc: moxart: read scr register without changing byte order

Browse source

commit d442632221 upstream.

Conversion from big-endian to native is done in a common function
mmc_app_send_scr(). Converting in moxart_transfer_pio() is extra.
Double conversion on a LE system returns an incorrect SCR value,
leads to errors:

mmc0: unrecognised SCR structure version 8
