[PATCH 0/3] sunxi: remove CONFIG_MMC?_CD_PIN

[Andre Przywara]

Since the dawn of time we had CONFIG_MMC?_CD_PIN defines for each
Allwinner board, which held the name for the respective MMC card
detect GPIO. These days we don't use that in U-Boot proper anymore
(and rely on DT for that, instead), so it's just for the SPL loading.
However the card detect is actually not needed there:
- We continue loading from the same boot media that the BootROM booted
  us from, so when we get to load from MMC, there is surely a card in
  the slot.
- The BROM already spoiled all efforts by unconditionally accessing the
  MMC bus, regardless of any card presence or not. We can't do more harm
  by doing the same.

This series removes the code checking the CD pin, and also the definition
from Kconfig and all defconfigs. On top there is a cleanup for the MMC
driver, which explains the reason for still also implementing the legacy
MMC interface.

Please have a look and test!

Thanks,
Andre
