ASoC: Intel: Skylake: Parse vendor tokens to build A-State table
A-State table is a power management table which allows the driver to
configure the DSP clock source corresponding to various load thresholds.
The table contains upto 3 A-State entries. The patch adds and parses the
corresponding A-State tokens to build the table.
