mmc_switch_part() is used for switching between hw partitions on eMMC (boot0, boot1, user, rpmb). There is no need to do that for SD card.

Is this a clean up or a bugfix? What are the visible effects for the user?

avb cmd fails for SD cards, as mmc_switch_part() fails after trying to access EXT_CSD register, which obviously is not available.
