This patch series adds power-supply properties for sdmmc nodes on Microchip boards.
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.

2.43.0
The sdmmc0 and sdmmc1 controllers are powered from 3.3V regulator.
Add vmmc-supply and vqmmc-supply properties to sdmmc nodes.
The sdmmc controller from SAM9X60 MPU doesn't support the IO voltage signaling/switching required by the UHS sd-card.
In order to use the sd high-speed mode, keep vqmmc at 3V3.

2.43.0
The sdmmc1 controller is powered from 3.3V regulator.
Add vmmc-supply and vqmmc-supply properties to sdmmc1 node.
The sdmmc controller from SAMA5D2 MPU has support for IO voltage signaling/switching required by the UHS sd-card.
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.
