power: supply: axp20x_usb_power: Add support for AXP192

Add support for the AXP192. It is most similar to the AXP202 but the current limits are different and the USB OTG status register has a different address (0x04 instead of 0x02). Signed-off-by: Aidan MacDonald <[email protected]> Signed-off-by: Sebastian Reichel <[email protected]>
