ASoC: Intel: bytcr_wm5102: Add BYT_WM5102_IN_MAP quirk

Unlike all designs supported sofar the Lenovo Yoga Tab 3 YT3-X90 does not
have its internal microphone (intmic) on IN3L with the headset microphone
on IN1L. Instead this tablet has the intmic on IN1L and the hsmic on IN2L.

Add a BYT_WM5102_IN_MAP quirk mechanism to allow selecting between
different input maps and add support for both setups with the current
settings being the default map.

The new INTMIC_IN1L_HSMIC_IN2L map is enabled by default on CHT because
the Lenovo Yoga Tab 3 YT3-X90 model is the only Cherry Trail design
currently supported. If different CHT designs turn up which need different
input maps we can add DMI quirks to select a different map later.

The userspace UCM profile also needs to know about this so
extend the components string with this info too.
