Add the QCS615 domain table to the in-kernel pd-mapper so that audio
subsystems no longer rely on the userspace pd-mapper daemon.
This enables proper initialization of ADSP and CDSP domains directly
from the kernel.

There definitely should be mpss_root_pd / mpss_wlan_pd, otherwise modem
will not load WiFi firmware.

Hi Konrad and Dmitry, This board does not contain an MPSS. WiFi is
handled by an independent WLAN module, which has its own internal PMU
and is already supported.

Please describe the full set for Talos-with-modem, the "S" variant
will work too, since any "extra" domains will simply remain inactive
