[media] tm6000: rewrite IR support
The IR support were broken on my tests with HVR-900H. Also, there were several issues on the current implementation. This patch is a major rewrite of the IR support for this - Improve debug messages; - Don't do polling for interrrupt based IR; - Add proper support for RC-5 protocol; - Always provide 16 bits for NEC and RC-5; - Fix polling code; - Split polling functions from URB Interrupt ones; - Don't hardcode the XTAL reference for tm6000 IR; - If a URB submit fails, retries after 100ms; - etc. Tested on Hauppauge HVR-900H, with RC-5 and NEC remotes. Issues on IR handling, on this device: - Repeat events aren't detected (neither on NEC or RC-5); - NEC codes are always provided with 16 bits. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
