Topology: Add support for 4ch 32bit 48kHz DMIC DAI
This patch restores the missing configuration into macro intel-generic-dmic.m4. Without this patch the 48 kHz DMIC DAI is not created. Both DMIC FIFOs are available at any channels number and PCM format so there is no need to delete a DAI when 4ch configuration is used. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>
