V4L/DVB (9066): Pinnacle Hybrid PCTV Pro (pctv310c) DVB-T support

This patch against latest mercurial makes DVB-T working on Pinnacle
Hybrid PCTV Pro (pctv310c).

In cx88-dvb.c, a specific zl10353_config is created with the if2
inferred from the old comment in the currently used config. It is then
used for attach, and i2c_gate_ctrl is set to NULL.

The entry in cx88-cards.c is modified with GPIO gathered from windows
with regspy, and DVB enabled. The frontend is set to
XC3028_FE_ZARLINK456 to match the zl10353_config.

It is working great with the freeview channels I can receive.
