soundwire: slave: use SDW_DISCO_LINK_ID()
use SDW_DISCO_LINK_ID() in slave code to extract field values instead of open coding masks and shift operations to extract link_id Signed-off-by: Vinod Koul <vkoul@kernel.org> Tested-by: Bard Liao <yung-chuan.liao@linux.intel.com> Link: https://lore.kernel.org/r/20200903114504.1202143-4-vkoul@kernel.org Signed-off-by: Vinod Koul <vkoul@kernel.org>
