i2c: sh_mobile: Add support for r8a774c0 (RZ/G2E)

[ Upstream commit 51243b73455f2d12cb82abffa7bc9028aec656e0 ]

Similarly to R-Car E3, RZ/G2E doesn't come with automatic
transmission registers, as such it is not considered compatible
with the existing fallback bindings.

Add SoC specific binding compatibility to allow for later
support for automatic transmission.
