mmc: squash lines for immediate return

Browse source 
These functions can be much simpler by squashing lines for immediate
return.

For *_bind() callbacks, they will be a simple wrapper function of an
upper-level bind API.

For mmc_set_{boot_bus_width,part_conf}, they will be a wrapper of
mmc_switch().
