V4L/DVB (3309): SAA7134: GPIO IRQ improvements
- Saa7134-core.c saa7134_irq(): Separate GPIO16 and GPIO18 handling. Call IR-remote-GPIO handler only if the GPIO IRQ is "owned" by it. Added infrastructure to branch out to a future I2C-IR IRQ handler. saa7134-core.c saa7134_hwinit2(): Enable only the one GPIO pin and edge to trigger an IRQ that is wired as keyup/keydown mask. IRQ will only be generated for an actual key-down event. saa7134-input.c flyvideo_codes[]: Replace numpad keys with normal ones. Put meaning to mystery keys. Change some key definitions to have their functions match their labels better. Fix typos. saa7134-input.c flydvb_codes[]: Added new table for the larger remote that comes with the LifeView FlyDVB series. saa7134-input.c build_key(): In IRQ mode, signal key-down and then key-up straight in one go.
