External Email
Use mmc_of_parse() to set the common host properties. That includes "bus- width", so parsing it can be removed from the driver.
But more importantly, "non-removable" is now respected, which fixes the usage of eMMC.

Tested myself on v5 without emmc, `mmc info` is unchanged for my sd card
