V4L/DVB (6607): saa7134: add support for reading Hauppauge eeprom

Browse Source 
Increased size of dev->eedata from 128 to 256, since the Hauppauge data begins
at byte 128.  This has been tested on boards with smaller eeproms, and caused
no problems.

Added comments to distinguish between the various versions of the HVR1110.
