Subject: [PATCH v2 5/8] arm64: dts: renesas: rzg3s-smarc: Fix the debug serial alias

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

The debug serial of the RZ/G3S is SCIF0 which is routed on the Renesas
RZ SMARC Carrier II board on the SER3_UART. Use serial3 alias for it for
better hardware description. Along with it, the chosen properties were
moved to the device tree corresponding to the RZ SMARC Carrier II board.

Fixes: adb4f0c5699c ("arm64: dts: renesas: Add initial support for RZ/G3S SMARC SoM")
Fixes: d1ae4200bb26 ("arm64: dts: renesas: Add initial device tree for RZ SMARC Carrier-II Board")
