[media] tm6000: Fix fast USB access quirk

The original patch used the fast USB quirk to enable fast access to
registers in the tm6000_read_write_usb(). The applied patch moved the
check to the tm6000_reset(), probably due to some merge conflicts.

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.
