topology: scripts: changes to accommodate different DAI types

This patch makes the following changes to make way for handling
different DAI types in tplg build script:

1. Define the test DAI type while processing m4 files
2. DAI format and DAI port might be relevant for other types of DAI's.
So use generic TEST_DAI_PORT and TEST_DAI_FORMAT instead of
TEST_SSP_PORT TEST_SSP_FORMAT
