soc: renesas: rz-sysc: Move RZ/V2H SoC detection to the SYS driver
As per the other SoC variant of the same family, the system controller
provides SoC ID in its own registers.

soc: renesas: rz-sysc: Add support for RZ/G3E family
Add SoC detection support for the RZ/G3E SoC. Also add support for
detecting the number of cores and the ETHOS-U55 NPU, and also detect PLL
mismatch for SW settings other than 1.7GHz.

soc: renesas: rz-sysc: Move RZ/G3S SoC detection to the SYSC driver
Now that we have SoC detection in the RZ SYSC driver, move the RZ/G3S
SoC detection to it. The SYSC provides SoC ID in its own registers.

soc: renesas: Add SYSC driver for Renesas RZ family
The RZ/G3S system controller (SYSC) has various registers that control
different functionalities. One of the exposed register offers
information about the SoC identification.
Add a driver that identifies the SoC. Later the driver will be extended
with other functionalities.
