Subject: [media] af9035: change dual mode boolean to bit field

For some reason there seems to be value	0x03 in eeprom for dual mode
(and 0x00 for single mode). Boolean is not always 1 bit wide - it
could be 8 bit wide too. Storing number 0x03 to boolean causes driver
to thing there is 4 tuners in some cases :o
Add also some comments regarding to eeprom.

Subject: [media] it913x: rename its tuner driver to tuner_it913x

There are three drivers with *it913x name on it, and they all
belong to the same device:
	a tuner, at it913x.c;
	a frontend: it913x-fe.c;
	a bridge: it913x.c, renamed to dvb_usb_it913x by the
building system.

This is confusing. Even more confusing are the two .c files with
the same name under different directories, with different contents
and different functions. So, prepend the tuner one.

This also breaks the out-of-tree compilation system.
