Convert sdhci-atmel documentation to yaml format. The new file will inherit from sdhci-common.yaml. Note: Add microchip,sama7g5-sdhci to compatible list as we already use it in the DT.

description:

|
When present, polarity on the SDCAL SoC pin is inverted. The default
|
|
polarity for this signal is described in the datasheet. For instance on
|
|
SAMA5D2, the pin is usually tied to the GND with a resistor and a
|
|
capacitor (see "SDMMC I/O Calibration" chapter).
