zork: Ignore input current and always ramp
CONFIG_CHARGE_RAMP_SW is designed to stop ramping if we are not
using enough current (so we are actually testing that the supplier
can give the current we ramp to). But this is checked using
charge_is_consuming_full_input_current(), which only tests for battery
charge between 2% and 95%. This fails to accurately reflect desire
for input current, because the low battery might want to charge
faster, and the AP might want extra power even with full battery.
For zork, change charge_is_consuming_full_input_current() to always
return true. This means we will always ramp. If we are not using the
full input current, and the supplier cannot deliver it when we do,
then we will detect the voltage drop and re-ramp, which seems fine.

BRANCH=zork
TEST=ramp with full battery
