The KPB output pin 2 is bound to DMIC1_HOST_PIPELINE_SINK, which still uses the old host copier name 'copier.host.18.1'. The host copier is now named after its PCM ID, 'host-copier.11.capture', which is also what the routes use. When the DMIC16k PCM is opened, the kernel cannot find the host copier in the KPB pin binding and fails to bind the route in sof_ipc4_get_queue_id():

warning: W007 route 'kpb.19.1' -> 'host-copier.11.capture':
'host-copier.11.capture' is not in the output pin binding of
'kpb.19.1' (fails when PCM 'DMIC16k' capture is opened)

Use the current host copier name. Only sof-dmic-4ch-wov changes.

What changed in this PR

Updates the DMIC WoV topology default configuration to bind the KPB output pin to the correctly named host copier widget, fixing route binding failures when opening the DMIC16k capture PCM.

Changes:

• Replace legacy host copier widget name (copier.host.18.1) with current PCM-ID-based name (host-copier.11.capture) for DMIC1_HOST_PIPELINE_SINK.

Should we use the DMIC1_HOST_PIPELINE_SINK macro instead of hard code 'host-copier.11.capture' in the route? This can prevent the mismatch between route and binding.
