usb: chipidea: msm: Mark device as runtime pm active
We're not properly marking the glue layer/wrapper device as runtime active, so runtime PM believes that the hardware state is inactive when we call pm_runtime_enable() in this driver. This causes a problem when the glue layer has a power domain associated with it, because runtime PM will go and disable the power domain to match the 'inactive' state of the device. Let's mark the device as active so that runtime PM doesn't improperly power down this device when it's actually active.
