ARM: dts: sunxi: A13/A31/A23/A33: Sync from Linux v5.18-rc1

Copy the devicetree source for the A10s/A13/GR8, A31(s), and A23/A33/R16
SoCs and all existing boards from the Linux v5.18-rc1 tag.

These changes are combined into one commit due to interdependencies:
 - The unit addresses were removed from bitbanged I2C buses, which
   drives a Kconfig default change. This affects sun5i-a13-utoo-p66.dts
   and sun6i-a31-colombus.dts.
 - The pinctrl nodes were renamed, including some used by the shared
   header sunxi-reference-design-tablet.dtsi.

To maintain ABI compatibility with existing LTS kernels, one change
moving some IP blocks to the r_intc interrupt controller is excluded.
This effectively reverts Linux commits 994e5818392c and 9fdef3c3d8c2.

This commit renames the file sun8i-r16-nintendo-nes-classic-edition.dts
to sun8i-r16-nintendo-nes-classic.dts to match the Linux tree.

This commit also adds the following new board devicetrees:
 - sun5i-a13-licheepi-one.dts
 - sun5i-a13-pocketbook-touch-lux-3.dts
 - sun5i-gr8-evb.dts
 - sun8i-a23-ippo-q8h-v1.2.dts
 - sun8i-a23-ippo-q8h-v5.dts
 - sun8i-a33-et-q8-v1.6.dts
 - sun8i-a33-ippo-q8h-v1.2.dts
 - sun8i-r16-nintendo-super-nes-classic.dts

As with the other SoCs, updates of note are conversion of GPIO pull-up
from pinconf to GPIO flags and renaming the detection GPIO properties in
the USB PHY nodes.
