[PATCH 2/3] ASoC: Intel: cht*: simplify card names for SOF uses

[Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>]

Blindly adding an sof- prefix to the card name is not user friendly
and causes UCM issues with a driver name truncated to 16 characters.

Simplify to use "sof-bytcht <codec_name>" pattern for all cht* machine
drivers. The sof- prefix is added by the core. A generic "SOF" driver
name is used, and UCMv2 will detect the configuration for this driver
by testing the card name.

Legacy uses are unmodified.
