V4L/DVB: saa7134: Fix IR support of some ASUS TV-FM 7135 variants

Some variants of the ASUS TV-FM 7135 are handled as the ASUSTeK P7131
Analog (card=146). However, by the time we find out, some
card-specific initialization is missed. In particular, the fact that
the IR is GPIO-based. Set it when we change the card type, and run
saa7134_input_init1().
