[PATCH] mmc: xenon_sdhci: Add missing common host capabilities

[Andre Heider <a.heider@gmail.com>]

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

Tested by G?rald on v7 emmc, which started working with this patch:
