[PATCH] input core

[Sascha Hauer]

This series adds an input driver core and ports some input driver over
to it.

Currently the input drivers are written as console drivers. The problem
with this is that we can only generate a character when a key is
pressed, but we can't ask for the current state of a key. One very
common usecase for buttons in a bootloader is to ask if the user is
holding a button while booting to go into a recovery mode or boot from
alternative sources. We should support this usecase and with this input
core we can.
A nice side effect is that the input driver get simpler since the input
core handles stuff like key repetition and fifos for the keys.
