pinctrl: axp209: add support for AXP813 GPIOs

Browse source

The AXP813 has only two GPIOs. GPIO0 can either be used as a GPIO, an
LDO regulator or an ADC. GPIO1 can be used either as a GPIO or an LDO
regulator.

Moreover, the status bit of the GPIOs when in input mode is not offset
by 4 unlike the AXP209.
