mb/google/rex/var/rex: Configure cpu power limits by battery status
When battery level is below critical level or battery is not present,
cpus need to run with a power optimized configuration to avoid platform
instabilities. This will check the current battery status and configure
cpu power limits properly.
BUG=b:296952944
TEST=Build rex0 and check cpu power limits are configured with
a performance efficient configuration and the platform boots to OS if
battery level is above the critical level. And check cpu power limits
are configured with a power optimized configuration and boots to OS
without an issue if battery is not present or battery level is at or
below critical level.
