usb: host: xhci-rcar: Simplify getting the firmware name for R-Car Gen3 

This patch simplifies getting the firmware name for R-Car Gen3.
Almost all R-Car Gen3 USB3.0 Host controllers use "V3". But,
r8a7795 ES1.x SoCs only should use "V2". Since the xhci-plat already
has the firmware_name of R-Car Gen3 as "V3", the xhci-rcar doesn't
need some members of rcar_quirks_match.

* - The V3 firmware is for r8a7796 (with good performance) and r8a7795 es2.0
* or later.
* - The V2 firmware can be used on both r8a7795 (es1.x) and r8a7796.
* - The V3 firmware is for almost all R-Car Gen3 (except r8a7795 ES1.x)
* - The V2 firmware is for r8a7795 ES1.x.
* - The V2 firmware is possible to use on R-Car Gen2. However, the V2 causes
* performance degradation. So, this driver continues to use the V1 if R-Car
* Gen2.
