[PATCH 3/7] usb: renesas_usbhs: Add compatible string for r8a7743/5

Fabrizio Castro <fabrizio.castro@...>

From: Biju Das <biju.das@...>

This patch adds support for r8a7743/5 SoCs. The Renesas RZ/G1[ME]
(R8A7743/5) usbhs is identical to the R-Car Gen2 family.

No driver change is needed due to the fallback compatible value
Adding the SoC-specific compatible values here has two purposes:
1. Document which SoCs have this hardware module,
2. Allow checkpatch to validate compatible values.
