[RFC] Input: Remove unused BUS IDs

[RFC] Input: Remove unused BUS IDs

[Jarkko Nikula]

There are a few BUS IDs that are not used anywhere in kernel tree:

- BUS_ISAPNP
  Has no changes or use in kernel git history
- BUS_GSC
  Was added by commit 6ab0f5cd3644 ("[PARISC] Update parisc specific input
  code from parisc tree") but never used
- BUS_ATARI
  Became unused after commit 6615c5b25e0b ("m68k: Atari input drivers
  cleanup")

I'm not familiar with the input and don't know is there use for these in
userspace. Therefore I didn't sort these IDs after removal.

actually /dev/uinput can still use these values if it wants to.
