V4L/DVB (12262): em28xx: Make sure the tuner is initialized if generic empia USB id was used

In cases where the device has a generic Empia USB ID, the call in the
precard setup phase did not set the tuner GPIO.  As a result, the tuner may
not be taken out of reset before attempting initialization in the analog
driver.

This problem was not seen before with the EVGA inDtube, since that particular
board has the analog GPIO setup to include taking the tuner out of reset.

Thanks to Andreas Lunderhage for testing patches and providing a remote debug
environment for the Pinnacle 320e.
