This patch series adds power-supply properties for sdmmc nodes on Microchip boards.
Changes in v4:
--------------
* Simplify the commit description for each board to have a better understanding.
Changes in v3:
--------------
* Update the commit description for each board in order to wrap the line at max 75 columns.
Changes in v2:
--------------
* Update the commit description for each board.
* The goal is to keep the vqmmc at 3V3 in order to use the sd high-speed mode.

In order to avoid the issues from the tuning procedure required by
the UHS cards, keep the vqmmc at 3V3 to use the sd high-speed mode.
Add vmmc-supply and vqmmc-supply properties to sdmmc0 node.
