Subject: [PATCH] driver: aspeed: g6: Fix PWMG0 pinctrl setting

The SCU offset for signal PWM8 in group PWM8G0 is wrong, fix it from
SCU414 to SCU4B4.
Besides that, When PWM8~15 of PWMG0 set it needs to clear SCU414 bits at
the same time.

Fixes: 2eda1cdec49f ("pinctrl: aspeed: Add AST2600 pinmux support")
