Adding a GRF GPIO controller labled "grf_gpio" to rk3328, currently
providing access to the GPIO_MUTE pin, which is manupulated by the
GRF_SOC_CON10 register.

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

Changes in v4:
- Use binding of "rockchip,rk3328-grf-gpio"

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.

applied to my dts64 branch, with 2 changes:
- reordered, please sort nodes without address alphabetically
- removed default disabled status
  The controlled pin is always present on the soc, so doesn't need
  to be enabled on a per-board level
