mb/google/brox/jubilant: Update CPU power limits

Browse source 
Update jubilant CPU PL4 from 9 watt to 14 watt for critical battery
boot. The maximum peak power is set at 14 watt which is 45W multiplied
by 32% efficiency.

Overriding power limits for AC power without battery:
PL1 (15000, 18000)
PL2 (41000, 41000)
PL4 (14)

BUG=b:364441688
BRANCH=None
TEST=Able to successfully boot on jubilant SKU1 and SKU2 with AC only.
     Test on AC 65W and 45W w/o battery, and check PL4 values from log.
