Commit Message

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?

Note that there are no in-kernel users (e.g. soc_device_match()) of the family
name. I'm not aware of any userspace users of /sys/devices/soc0/family.
