[PATCH 5.5 030/257] usb: ucsi: ccg: disable runtime pm during fw flashing

[Greg Kroah-Hartman]

From: Ajay Gupta <ajayg@xxxxxxxxxx>

[ Upstream commit 57a5e5f936be583d2c6cef3661c169e3ea4bf922 ]

Ucsi ppm is unregistered during fw flashing so disable
runtime pm also and reenable after fw flashing is completed
and ppm is re-registered.
