ARM: dts: sun7i: Sync from Linux v5.18-rc1

Copy the devicetree source for the A20 SoC and all existing boards
verbatim from the Linux v5.18-rc1 tag.

This commit also adds the following new board devicetrees:
 - sun7i-a20-haoyu-marsboard.dts
 - sun7i-a20-linutronix-testbox-v2.dts
 - sun7i-a20-olinuxino-lime-emmc.dts

This update includes changes to the USB PHY detection GPIO properties
which are needed to convert that driver to use the DM GPIO framework.
