Add support for Anbernic's RG-DS audio amplifiers, powered by
Awinic AW87391 amplifier ICs. These chips typically require an
init sequence provided by firmware, but the manufacturer did not
provide firmware in this case. As a result we had to hard-code
the init sequence and use a device specific binding (rather than
a binding just for the aw87391).
