soc: renesas: Identify more R-Car Gen3e SoCs

Add support for identifying the remaining R-Car Gen3e SoCs: R-Car H3e
(R8A779M0), M3e (R8A779M2), M3Ne (R8A779M4), M3Ne-2G (R8A779M5), E3e
(R8A779M6), D3e (R8A779M7), and H3Ne (R8A779M8).

As these are different gradings of the already supported R-Car Gen3
SoCs, support for them is enabled through the existing ARCH_R8A779*
configuration symbols.
