[PATCH 0/2] mach-meson: port dwc2_otg usage to CONFIG_DM_USB_GADGET=y

[Mattijs Korpershoek]

While working on some USB bugs on the VIM3L board, we stumbled upon the fact
that mach-meson still uses legacy board_usb_*() functions instead of using DM [1]

This series aim to switch the g12a based boards to use CONFIG_DM_USB_GADGET and
removes the board_usb_*() logic.

* The first patch adds mode switching in the dwc3-meson-g12a glue driver whenever
  the dwc2 otg driver is probed()/removed().

* The second patch enables the config option and cleans up all board_usb_*().

This has been mainly tested with khadas-vim3l_android_defconfig using fastboot:

=> fastboot usb 0

=> # hit Ctrl-c

Other tests:
* ums 0 mmc 2 # can list / mount partitions from host
* usb start; usb storage # list usb thumb drive
* all defconfigs have been build tested
