[RFC PATCH 3/3] ASoC: Intel: cht: Add Yoga Book SOF topology filename

The Cherry Trail SOF machine selection requires each matched machine to
provide a topology filename. Without one, atom_machine_select() rejects
the Yoga Book entry and the SOF sound card cannot register.

Associate the RT5677 Yoga Book machine with sof-cht-rt5677.tplg. The
IPC3 driver then loads intel/sof-tplg/sof-cht-rt5677.tplg through the
standard firmware search path.

The matching topology sources are maintained in the SOF project and
must be merged and distributed separately; this kernel change only
provides the standard firmware filename.
