ASoC: amd: acp: update dmic_num logic for acp pdm dmic

[ Upstream commit 5902e1f ]

Currently there is no mechanism to read dmic_num in mach_params
structure. In this scenario mach_params->dmic_num check always
returns 0 which fails to add component string for dmic.
Update the condition check with acp pdm dmic quirk check and
pass the dmic_num as 1.
