Topology: NHLT: Intel: Fix mono DMIC configure for MTL platform

This change fixes the blob generator for mono microphone
configuration. As difference to previous platforms the FIFO packer
mono/stereo mode set up in OUTCONTROLx IPM_SOURCE_MODE bit-field.
The previous code version hard-codes the FIFO packer to stereo
mode without support for mono.

As a fix if only one microphone is enabled for dmic0 or dmic1,
then the corresponding IPM_SOURCE_MODE in OUTCONTROL0 or OUTCONTROL1
is set to 0. Otherwise it is set to 1 for stereo mode.
