usb: dwc3-msm: Resume PHY before notify_connect on start_host
Currently as a part of host cable connection, we are notifying
cable connect to phy driver first and then resuming the PHY. This
leads to bus resume case running instead of the cable connect
case resume, hence the phy driver does not vote for the LDOs. As
a result, PHY goes into bad state. Fix this by first resuming PHY
so that cable connect case resume runs.
