The commit commit [33f4acd3b2: ALSA: hda - Enable mic mute hotkey
and LEDs for an HP machine] introduced a quirk for a HP machine
involving with the input event handling. Although the relevant code
is protected via IS_ENABLED(CONFIG_INPUT), this doesn't suffice when
the audio driver is built in while the input is module.
As an easy workaround, this patch forcibly selects CONFIG_INPUT in
Kconfig. This shouldn't be a practical problem since CONFIG_INPUT is
almost mandatory for all systems. Also, this allows to remove the
ugly ifdefs in the code.
