[PATCH] arm64: allwinner: a64: orangepi-zero-plus2: add usb otg

[Jagan Teki <jagannadh.teki-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Add usb otg support for orangepi-zero-plus2 board:
- Add usb_otg node with dr_mode as 'otg'
- USB0-IDDET connected to PA21
- VBUS connected through DCIN which always on

Tested mass storage function.

Note: Anyone please check vbus connection [1]
Since it is connected through DCIN of vcc-5v, I've added vcc-5v0
regulator for the same and attached to usb0_vbus-supply but it is
disabling during kernel boot.
