148bcca9ad soc: renesas: Prefer memcpy() over strcpy() 
strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors. So, use memcpy() as a safe replacement.

This is a previous step in the path to remove the strcpy() function
entirely from the kernel.

Add support for R-Car V3U (R8A779A0) SoC power areas and register
access, because register specification differs from R-Car Gen2/3.

Inspired by patches in the BSP by Tho Vu.
