media: rc: keymaps: add missing MODULE_DESCRIPTION to keymaps

When building the modules 'modpost' warns about missing MODULE_DESCRIPTION.

Since almost none of the rc keymap modules have this, it produces a lot of
warnings.

As a first step to fixing all media modules, add this line to all keymaps.
The description should be a human-readable string describing the remote
or the remote controller that the keymap can be used with.

Note that keymaps/rc-cec.c is actually compiled into the rc-core, so that
is the sole keymap source that didn't need this.

media: rc: Prefer KEY_NUMERIC_* for number buttons on remotes

Prefer KEY_NUMERIC_* for number buttons on remotes. Now all the remotes
use KEY_NUMERIC_[0-9] for the number buttons rather than keys that
could be affected by modifiers (Caps-Lock, or Num-Lock) or regional
keymaps.

Created using:
sed -i 's/KEY_\([0-9]\) /KEY_NUMERIC_\1 /' *.c
sed -i 's/KEY_\([0-9]\)}/KEY_NUMERIC_\1}/' *.c

media: rc: rename RC_TYPE_* to RC_PROTO_* and RC_BIT_* to RC_PROTO_BIT_*

RC_TYPE is confusing and it's just the protocol. So rename it.

[media] ati_remote: switch to single-byte scancodes

The ati_remote driver currently uses 2-byte scancodes. However, one of
those bytes is actually a checksum and therefore shouldn't be considered
as part of the scancode.

Fix the driver to only use the actual data byte as a scancode and to
check the checksum itself. Update the bundled keymaps accordingly.

Since ati_remote was only migrated to the rc subsystem for 3.2, the
previous scancodes weren't emitted on any stable kernel.
