[PATCH v2 0/4] Add Anbernic RG-Nano

[Chris Morgan <macroalpha82@gmail.com>]

From: Chris Morgan <macromorgan@hotmail.com>

Add support for the Anbernic RG-Nano handheld gaming device

Changes since V1:
 - Added additional pwm pin configs to sun8i-v3s.dtsi and removed
   default config for pwm0 in lieu of defining it for each board.
 - Noted in patch notes that additional hardware of UART debug port,
   USB port (in gadget mode) also work, and that USB host mode does
   not work.
 - Identified GPIO responsible for enabling external speaker amplifier
   and defined it, allowing onboard audio to work.
 - Removed ac_power_supply node.
 - Set regulator min and max values to the same value as defined in the
   schematics.
 - Removed definition for reg_ldo1. This regulator is hardware
   configured so the value did not affect anything, however the driver
   must be updated to support the correct value of 3.3v in this case.
 - Removed usb0_id_det-gpios as I cannot confirm these are correct.
