usb: dwc2: fix a race with external vbus supply
[ Upstream commit 41ee1ea21052583eaf5487dfa0d0c907c9667548 ]
There's a race with root hub resume, when using external vbus supply.
Root hub gets resumed, but runtime pm autosuspend runs as external vbus
supply isn't enabled. So, host never exit from power down properly.
Initialize vbus external supply before, rater that after hub resume.
Fixes: 531ef5ebea96 ("usb: dwc2: add support for host mode external
vbus supply")
