mmc: block: Refactor mmc_blk_part_switch()
Instead of passing a struct mmc_blk_data * to mmc_blk_part_switch()
let's pass the actual partition type we want to switch to. This
is necessary in order not to have a block device with a backing
mmc_blk_data and request queue and all for every hardware partition,
such as RPMB.
