[U-Boot] [PATCH V3 03/10] mmc: uniphier-sd: Add Renesas RCar quirks

[Marek Vasut]

Add a quirk to identify that the controller is Renesas RCar variant
of the Matsushita SD IP and another quirk indicating it can support
Renesas RCar HS200/HS400/SDR104 modes.

V2: No changes
V3: Add RCar Gen2 quirk, since the Gen2 IP is slightly different
