Nami: Make Vayne shutdown at 4% battery charge
Currently, Vayne and all other Nami's shutdown when battery charge
(=soc) goes below 3%. This patch makes Vayne set shutdown charge
level to 4% to match Powerd's threshold.
When system is running or in suspend, Vayne behaves as follows:
1. Powerd shuts down system when soc < 4. (EC also catches soc < 4 but
takes no action.) If Powerd fails to shut down system or system is
in suspend, EC forces system to shut down.
2. System shuts down.
3. charger task cuts off battery.
When system is off or in suspend, EC cuts off battery in 30 secs after
soc <= 4%.
