There are instances: sdhci0: 8bit bus width, max 200 MBps sdhci1: 4bit bus width, max 100 MBps sdhci2: 4bit bus width, max 100 MBps The PHY used for 8 bit instance is same as the PHY for the 4 bit instance. Therefore, introduce a new bus width independent compatible for AM62 SoC that uses the driver data required for 4 bit instance.
