aw_gpio: support Allwinner D1 GPIO

The GPIO controls the multiplexing of the D1 pins to its peripherals,
so this adds the definitions needed by the aw_gpio driver to support
the D1.

Also, this modifies the aw_gpio driver to support the differences of
the D1 controller:

- pins can have up to 15 functions
- each port is mapped with an alignment of 0x30
- CFG registers have 4 bits per pin
- DRV registers have 4 bits per pin
- the offset of PULL registers is 0x24

riscv: enable allwinner RTC

For the Allwinner D1 (Nehza) SBC.

This RTC driver is also a clock provider, which registers two fixed
clocks. In all the devices we currently support, the names of the clocks
are present in the "clock-output-names" property of the device tree.
This is not the case for the D1 DTS, as this property does not appear in
upstream. Therefore the clock definitions are statically assigned a
name, which is overridden when specified.
