- ti,otap-del-sel: Output Tap Delay select

+Optional Properties (Required for ti,am654-sdhci-5.1 and ti,j721e-sdhci-8bit):
- ti,trm-icp: DLL trim select
- ti,driver-strength-ohm: driver strength in ohms.
Valid values are 33, 40, 50, 66 and 100 ohms.
+Optional Properties:
+ - ti,strobe-sel: strobe select delay for HS400 speed mode. Default value: 0x0.
Example:
Add binding documentation for mmc host controllers present on TI's J721E SOC. The 4 bit IP on J721E doesn't have a phy DLL so make DLL related properties as optional for that compatible. Also add an optional strobe-sel property used for HS400 speed mode.
