ASoC: SOF: add default IPC capability and file paths

This patch adds a default IPC type for each platform, along with file
paths to be used for each IPC type. To make reviews simpler, we only
modify platform descriptors in this table, the information will be
used in the next patch.

The Intel IPCv4 is only supported on Intel platforms after APL, and
not by default. In follow-up patches, support for SKL and KBL will be
added, and in those two cases the IPCv4 will be the default (and only
supported mode).
