Protection domain mapper is a QMI service providing mapping between
'protection domains' and services supported / allowed in these domains.
For example such mapping is required for loading of the WiFi firmware or
for properly starting up the UCSI / altmode / battery manager support.

The existing userspace implementation has several issue. It doesn't play
well with CONFIG_EXTRA_FIRMWARE, it doesn't reread the JSON files if the
firmware location is changed (or if the firmware was not available at
the time pd-mapper was started but the corresponding directory is
mounted later), etc.

However this configuration is largely static and common between
different platforms. Provide in-kernel service implementing static
per-platform data.

Unlike previous revisions of the patchset, this iteration uses static
configuration per platform, rather than building it dynamically from the
list of DSPs being started.
