platform: msm: Set USB speed to SUPER before calling notifier
Currently we set the USB speed to SUPER after calling vbus/id
notifier callback. As a part of cable connect, is USB speed
is set to SUPER after connect resume_work is called, then we
do not initialise the SSPHY. So clocks are OFF.
But as part of cable disconnect, if USB speed is set to SUPER
before disconnect resume_work is called, then we try to
suspend SSPHY resulting in unclocked access.
Fix this by mandatorily setting USB speed to SUPER before
queuing VBUS/ID notifier.
