Subject: [PATCH v2 05/15] soc: renesas: rz-sysc: Move RZ/G3S SoC detection to the SYSC driver

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

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.

Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Changes in v2:
- this was handled though patch 05/16 in v1 
- provide SoC specific init data through the SoC specific driver
