V4L/DVB (3393): Move all IR keymaps to ir-common module

- All the keymaps have the same structure, and can be shared between different
chips, so it makes no sense having them scattered between the input files.
This aggregates them all at ir-common module.
- Added new Hauppauge remote (Hauppauge grey), contributed by J.O. Aho
  <trizt@iname.com> (with some small changes)
  Changed KEY_KPx (keypad numerals) references to KEY_x, to avoid problems
  when NumLock is off (suggested by Peter Missel <peter.missel@onlinehome.de>)
- Some cleanups at IR code
