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.

Adding Marek to loop, can you test this patch on MOX A to verify that it
does not break MOX uSD and SDIO support?
(PS: Andre, for one week I would not be available, therefore in this
time I would not be able to test or review Armada 3720 patches...)
I'll also be on vacation next week. Sorry, I was not able to follow all
discussions on these Armada related patches lately. Could someone please
summarize, which patches (fixes) are "okay" for merging in this rc stage
(rc4)? That would really be helpful.
Thanks,
Stefan
