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 defined in the syscon GRF_SOC_CON10.

The GPIO_MUTE pin is referred to as <&gpio-mute 1>.

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

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.
