From: Levin Du <djw@t-chip.com.cn>

Adding a new gpio controller named "gpio_mute" to rk3328, providing
access to the GPIO_MUTE pin, which is manupulated by the GRF_SOC_CON10
register.

The GPIO_MUTE pin is referred to as <&gpio_mute 0>.

Signed-off-by: Levin Du <djw@t-chip.com.cn>

Changes in v3:
- Use dedicated "rockchip,rk3328-gpio-mute" driver

Changes in v2:
- Rename gpio_syscon10 to gpio_mute in rk3328.dtsi

Changes in v1:
- Split from V0 and add to rk3328.dtsi for general use.
