ALSA: hda: generic: Add a helper for mic-mute LED with LED classdev
A new helper, snd_hda_gen_add_micmute_led_cdev(), is introduced here
for creating a LED classdev and setting up the hook to the capture
control for controlling the mic-mute LED to follow the capture switch
change. This will replace the existing users of
snd_hda_gen_add_micmute_led() in later patches.
Also, introduce a new kconfig CONFIG_SND_HDA_GENERIC_LEDS, to indicate
the usage of mute / mic-mute LED helpers. It's selected by the codec
drivers (Realtek, Conexant and Sigmatel), while it selects the
necessary LED class dependencies.
