[PATCH v3 4/7] pinctrl: renesas: rzg2l: Add support for RZ/G3E SoC

[Biju Das <biju.das.jz@xxxxxxxxxxxxxx>]

Add pinctrl driver support for RZ/G3E SoC.

Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>
---
v2->v3:
 * Replaced RZG3E_* macro with generic PORT_* macro.
 * Added ports based on hardware indices.
 * Replaced macros WDTUDF_CA->WDTUDFCA and WDTUDF_CM->WDTUDFCM.
 * Replaced macro QSD0_*->SD0*.
v1->v2:
 * No change.
