From: Levin Du <djw@xxxxxxxxxxxxx>
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>.

- Rename gpio_syscon10 to gpio_mute in rk3328.dtsi
Changes in v1:
- Split from V0 and add to rk3328.dtsi for general use.
