mmc: litex_mmc: Set width from linux request

Browse source

Previously, the litex_mmc driver force the 4 bits bus width.
This means that the gateware with 1 bit bus width is not fit.
However, litesdcard does support setting bus width, which
make the 1 bit bus width gateware possible to be used.

Add logic for setting bus width in the set_ios() function.
