V4L/DVB: bttv: Move I2C IR initialization

Browse Source 
commit 2434466432 upstream.

Move I2C IR initialization from just after I2C bus setup to right
before non-I2C IR initialization. This avoids the case where an I2C IR
device is blocking audio support (at least the PV951 suffers from
this). It is also more logical to group IR support together,
regardless of the connectivity.

This fixes bug #15184:
