ASoC: SOF: acpi led support for switch controls
Currently sof doesn't support acpi leds with mute switches. So implement
acpi leds following quite shamelessly existing HDA implementation by
Takashi Iwai.
Mute leds can be enabled in topology by adding led and direction token
in switch control private data.
