Subject: [PATCH v2] arm64: qcom: pd-mapper: Add QCS615 power domain mappings

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.

Changelog:

v2:
  - Added mpss_root_pd and mpss_wlan_pd for Talos/SM6150 variants, as Wi‑Fi
    firmware is loaded via MPSS (icnss). Confirmed by modemr.jsn/root_pd and
    modemuw.jsn/wlan_pd from Redmi Note 7 Pro firmware
  - v1-link: https://lore.kernel.org/all/20260122111318.500262-1-le.qi@oss.qualcomm.com/
