[coreboot] problem after "convert to ASL 2.0"

[Andrew A . I .]

Hello, Elyes!

After "Convert to ASL 2.0 syntax" set of commits to current coreboot branch, i lost the data of battery current on BAT state from:

cat /sys/class/power_supply/BAT0/current_now  
0

On AC state (charging) data is present:

cat /sys/class/power_supply/BAT0/current_now 

1346000

Checkout to coreboot tag/4.13 is fixing the problem.

But system was very unstable with:

System:
