charge_state_v2: Limit i/p current to meet allowed MAX i/p system power
If battery is not present, input current is set to PD_MAX_CURRENT_MA.
If the input power set is greater than the maximum allowed system power,
system might get damaged. Hence, limit the input current to meet maximum
allowed input system power.
BUG=chrome-os-partner:58498
BRANCH=none
TEST=Manually tested on Reef. Removed the battery & using 'charger'
console command observed the following.
With Zinger charger at 20V - Input current is set to 2.25A
With Type-C & other chargers - Input current is set to 3A
