[PATCH] dvb: ttpci: av7110: RC5+ remote control support

Improved remote control support for av7110-based cards:
o extended rc5 protocol, firmware >= 0x2620 required
o key-up timer slightly adjusted
o completely moved remote control code to av7110_ir.c
o support for multiple ir receivers
o for now, all av7110 cards share the same ir configuration and event device
