conf/ucm: bytcr-rt5651: Add support for mic input on various pins

Note this commit replaces the pre-existing "Handset Microphone" and
"Main Microphone" options, these come from the first commit of the
bytcr-rt5651 UCM profile and were based on wrong assumptions about the
input mappings. None of the existing devices has the Hand/Headset mic
on IN1 as these options assumed.

The rt5651 is used in various configurations with the Internal Mic(s)
hooked up to IN1, IN2, or to IN1 and IN2 and the Headset Mic hooked up
to IN3.

Add support for all these to the generic bytcr-rt5651 profile and name
them accotding to their input + functions.

A follow up commit will add specialized longname configs which
will only expose the inputs actually used on the board with that
longname.
