This change is depends on the below patch series:
https://lore.kernel.org/patchwork/cover/1418814/

Changes since V4:
- Included gpio header in proper order and moved default pins
configs to soc file as suggested by Stephen Boyd.

Changes since V3:
- Changed pinconfig names as suggested by Konrad Dybcio.
- Removed extra lines and aligned some of lines as
suggested by Bjorn Andersson.

Change since V2:
- Added leading zero's for register address and "qcom,sc7280-sdhci"
string in compatible as suggested by Stephen Boyd and Doug.
- Removed max-frequency flag, no-mmc and no-sdio flags
for Sd card as suggested by Doug and Stephen Boyd.
- Moved non-removable, no-sd, no-sdio and some pin config
changes from soc to board dts file as suggested by Doug.
- Removed sleep state for CD line and drive-strength for input pins
as suggested by Doug.
- Updated bus vote numbers for eMMC and SD card.

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.
