The Anbernic RG-DS uses two AW87391 ICs at 0x58 and 0x5B on i2c2. However, the manufacturer did not provide a firmware file, only a sequence of register writes to each device to enable and disable them. Add support for this *specific* configuration in the AW87390 driver. Since we are relying on a device specific sequence I am using a device specific compatible string. This driver does not currently support the aw87391 for any other device as I have none to test with valid firmware. Attempts to create firmware with the AwinicSCPv4 have not been successful. --- c1b835eefb7887266ac39573054a224a8e32207f
