From: Levin Du <djw@xxxxxxxxxxxxx>
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@xxxxxxxxxxxxx>

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.
