V4L/DVB (11767): cx23885: Add preliminary support for the HVR1270

The patch means the board will be recognised, and the parts brought
out of reset correctly. This patches depends on the centralized GPIO
patch to be merged. What's missing before the HVR-1270 will function
for DTV? The model# needs to be added to avoid 'unknown model'
output and the LG3305/Tuner need to be attached in cx23885-dvb.c
