[PATCH v1 3/3] pinctrl: pinctrl-aspeed-g6: Add sgpio pinctrl settings

From: Steven Lee
Date: Mon May 24 2021 - 07:14:40 EST


AST2600 supports 2 SGPIO master interfaces and 2 SGPIO slave interfaces.
Current pinctrl driver only define the first sgpio master and slave
interfaces.
The sencond SGPIO master and slave interfaces should be added in
pinctrl driver as well.
