ec/lenovo/h8: Implement ACPI methods to set battery thresholds
There are two known reverse-engineered ways to manage battery
thresholds.
This patch implements them and adds a way to enable them for
different mainboards.
Tested on W530 with 4.18.3-gentoo kernel and X220 with 4.20.11.
Works fine with new Linux userspace API for controlling battery
thresholds, available since 4.17.
(/sys/class/power_supply/BAT0/charge_(start|stop)_threshold).
The new API is supported by TLP (you might need to set NATACPI_ENABLE=1
in /etc/tlp.conf).
tpacpi-bat works fine too.
