ucm2: sof-soundwire: Add support for CS42L43B variant

Browse source 
From UCM point of view CS42L43B codec adds 2 new decimators and removes
a control to change Decimator 1 mode from base CS42L43. Thus reuse
CS42L43 files, and guard the CS42L43B additions behind a condition
that the new Decimator controls exist.

Closes: https://github.com/alsa-project/alsa-ucm-conf/pull/665
