rockchip: Migrate to use DM_USB_GADGET on RK3328
USB gadget is not working fully as expected on RK3328, it uses a
board_usb_init() function to initialize the DWC2 OTG port.
The board_usb_init() function does not intgrate with the generic phy
framework and as a result the USB phy is not properly configured before
or after USB gadget use.
Having both USB_DWC2 and DWC2_OTG enabled for the same board is also
causing some issues.
Trying to use rockusb or ums command after usb stop result in a freeze
due to usb stop is putting the phy in a suspended state.
=> usb start
=> usb stop
=> ums 0 mmc 0
--> freeze due to usb phy is suspended <--
Fix this by only using one of USB_DWC2 (host) or DWC2_OTG (peripheral)
depending on the most likely usage of the otg port and by migrating to
use DM_USB_GADGET instead of a board_usb_init() function.
The nanopi-r2 and orangepi-r1-plus variants share OTG and power using a
Type-C connector, mark these boards dr_mode as peripheral, the most
likely usage is for recovery and image download.
The rock64 and roc-cc currently use dr_mode as host, remove the DWC2_OTG
driver from these boards to ensure that the USB_DWC2 driver is used.
The rock-pi-e board does not enable the usb20_otg node so both USB_DWC2
and DWC2_OTG is removed from this board.
Enable RockUSB and UMS on all boards with a otg port in peripheral mode.
Also with the migration to DM_USB_GADGET completed the U-Boot specific
change to reorder usb nodes in the soc device tree can be reverted.
