V4L/DVB: IR/imon: convert to ir-core protocol change handling

Drop the imon driver's internal protocol definitions in favor of using
those provided by ir-core. Should make ir-keytable Just Work for
switching protocol on the fly on the imon devices that support both the
native imon remotes and mce remotes.

The imon-no-pad-stabilize pseudo-protocol was dropped as a protocol, and
converted to a separate modprobe option (which it probably should have
been in the first place). On the TODO list is to convert this to an as yet
unwritten protocol-specific options framework.

While the mce remotes obviously map to IR_TYPE_RC6, I've yet to look at
what the actual ir signals from the native imon remotes are, so for the
moment, imon native ir is mapped to IR_TYPE_OTHER. Nailing it down more
accurately is also on the TODO list.
