mb/google/poppy/variants/atlas: update DMIC NHLT configuration

From coreboot side, include DMIC 4ch NHLT configuration and its
DMIC blob. In OS side, cras picks the needed channels using UCM's
channel map configuration.
So, this patch updates to include DMIC 4ch config.

BUG=b:79158926
TEST=Verified 4-ch record with arecord
TEST=Also verified internal mic record with cras using
 'cras_test_client --capture_file dmic.raw --rate 48000
	 --num_channels 2 --duration 10'
