scarlet: Bump the hard-coded battery current
scarlet: Bump the hard-coded battery current

For scarlet, the battery desired current is always overridden
by charger_profile_override().
As scarlet has a dumb battery, we just need a hard-coded
placeholder for the fuel gauge.

'firmware_ECCharging' test doesn't expect charger target current
to go higher than battery desired current, so we need to bump this
hard-coded battery desired current to pass the test.

BUG=b:111837457
BRANCH=scarlet
TEST=battery command shows I-desired is 4000mA
TEST=firmware_ECCharging passes when battery is not full
