From: Levin Du <redacted>

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>.

Signed-off-by: Levin Du <redacted>

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
