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. NOTE: this is an RFC / RFC, the domain mapping data might be inaccurate (especially for SM6xxx and SC7xxx platforms), which is reflected by several TODO and FIXME comments in the code.
