[PATCH 3/3] soc: renesas: Identify RZ/G2M

[Biju Das <biju.das@xxxxxxxxxxxxxx>]

This patch adds support for identifying the RZ/G2M (r8a774a1) SoC.
It corrects the original RZ/G SoC family name to RZ/G1 and also 
adds support for the new RZ/G2 SoC family.

This patch corrects the RZ/G family name. Can it be 
considered for 4.19?
