soc: renesas: r8a779a0-sysc: Fix A2DP1 and A2CV[2357] PDR values
...
The PDR values for the A2DP1 and A2CV[2357] power areas on R-Car V3U are
incorrect (copied-and-pasted from A2DP0 and A2CV[0146]).
Fix them.

soc: renesas: rcar-gen4-sysc: Introduce R-Car Gen4 SYSC driver
...
According to the official website [1], the R-Car V3U SoC is based
on the R-Car Gen4 architecture. So, introduce R-Car Gen4 SYSC
driver.

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.

soc: renesas: r8a779a0-sysc: Add r8a779a0 support
...
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.
