ASoC: SOF: Intel: don't check number of sdw links when set dmic_fixup

Browse Source 
[ Upstream commit 56a677293509b2a0d39ac8d02b583c1ab1fe4d94 ]

Currently, we assume that the PCH DMIC pins are pin-muxed with SoundWire
links. However, we do see a HW design that use PCH DMIC along with 3
SoundWire links. Remove the check now.
With this change the PCM DMIC will be presented if it is reported by the
BIOS irrespective of whether there are SDW links present or not.
