arm64: dts: rockchip: add Awinic aw87391 amplifiers for Anbernic RG-DS
Add support for the two Awinic aw87391 audio amplifiers used in the
Anbernic RG-DS. These amplifiers require a specific init sequence to
start which is usually provided by a firmware file, but in our case
the manufacturer only provided the sequence. As a result, we hard-code
a device specific compatible.
Additionally, add support for the VDD regulator used to power both
amplifiers. Note that the amps can accept and respond to i2c commands
even without regulator power (perhaps due to a secondary power source)
but cannot play audio.
