platform/x86: Add new msi-ec driver
Add a new driver to allow various MSI laptops' functionalities to be
controlled from userspace. This includes such features as power
profiles (aka shift modes), fan speed, charge thresholds, LEDs, etc.
This driver contains EC memory configurations for different firmware
versions and exports battery charge thresholds to userspace (note,
that start and end thresholds control the same EC parameter
and are always 10% apart).
