Subject: [PATCH] ARM: sun5i: dt: Fixup mmc bindings
1) Now that we're no longer overriding the caps set by mmc_of_parse we need
to set cd-inverted for our card detection to work.
2) Now that we no longer claim UHS modes support we will never use any DDR
modes, so drive-strength 2 is enough for the mmc data pins.
3) mmc1 on the A13 is not routed to any pins, and thus unusable, remove it
from the dtsi
