zork: Adjust AP power limits
Adjust EC config settings that control how much battery charge and
AC power is required to allow AP to boot, to align with how much
power the HW actually needs.
EC will boot AP to depthcharge if: (BAT >= 4%) || (AC >= 50W)
CONFIG_CHARGER_LIMIT_* is not set, so there is no additional restriction
on Depthcharge to boot OS.
BUG=b:162938720
BRANCH=zork
TEST=boot with:
- various battery and AC levels,
- plugged/unplugged battery,
- locked/unlocked EC,
- swsync GBB disabled/enabled
