glados: isl9237: add HW charge ramping
Add HW charge ramping option and enable on glados.
Modify charge_manager to enable/disable HW charge ramping
when option is defined.
Unfortunately, the isl9237 doesn't have a way to determine
what the input current limit has settled on, so the EC will
always report the max input current for that supplier.
BUG=chrome-os-partner:47335
BRANCH=none
TEST=plug in CDP, SDP, DCP, type-C, and PD charger. Make sure
we ramp to a reasonable value for the correct suppliers.
Make sure we don't ramp for type-C and PD chargers.
