usb: dwc3-meson-g12a: force mode on child add/removal
arch/mach-meson has some custom usb logic, in particular:
* on board_usb_init(), we force USB_DR_MODE_PERIPHERAL
* on board_usb_cleanup(), we force USB_DR_MODE_HOST
With DM_USB_GADGET=y, board_usb_init/cleanup() are no
longer used when we call usb_gadget_initialize().
Instead, the generic (from udc-uclass) initialization/release is
called, which itself calls the controller driver's probe()/remove().
Therefore, enabling DM_USB_GADGET=y will mean that this mode
switching will break.
To prepare for enabling DM_USB_GADGET, perform the mode switching
when the "amlogic,meson-g12a-usb" (dwc2) driver is
probed()/removed() instead.
This is achieved via the glue driver, which gets notified each time one
of its children is probed()/removed.
Note: this change should be harmless without DM_USB_GADGET=y
because the amlogic-g12a-usb driver is not probed via driver model.
