This change is depends on the below patch series:
https://lore.kernel.org/patchwork/project/lkml/list/?series=488871
https://lore.kernel.org/patchwork/project/lkml/list/?series=489530
https://lore.kernel.org/patchwork/project/lkml/list/?series=488429

Changes since V1:
	- Moved SDHC nodes as suggested by Bjorn Andersson.
	- Dropped "pinconf-" prefix as suggested by Bjorn Andersson.
	- Removed extra newlines as suggested by Konrad Dybcio.
	- Changed sd-cd pin to bias-pull-up in sdc2_off as suggested by
	  Veerabhadrarao Badiganti.
	- Added bandwidth votes for eMMC and SD card.
