[SRU][R][PATCH 10/18] ASoC: SDCA: Allow sample width wild cards in set_usage()

[Chris Chiu]

From: Simon Trimmer <simont at opensource.cirrus.com>

BugLink: https://bugs.launchpad.net/bugs/2139391

The SDCA spec allows the sample rate and width to be wild cards, but the
current implementation of set_usage() only checked for a wild card of
the sample rate.
