[PATCH v1 2/3] tools/LPMD: Add Makefile

[Maciej Wieczor-Retman]

From: Fabio M. De Francesco <fabio.m.de.francesco@xxxxxxxxxxxxxxx>

The Makefile builds both intel_lpmd and intel_lpmd_control, generates
config.h and lpmd-resource.c at build time, and installs binaries,
systemd unit, D-Bus policy, and XML configuration files.

The build warns and fails if the dependencies listed in
tools/power/x86/intel-lpmd/README.md are not installed.
