bq2598x: ryu: take into account hardware input current optimizer
Take profit of the hardware input current ramping/back-off integrated
in the BQ2589x charger by setting the current limits higher for BC1.2
USB modes and letting the hardware adjust to the actual charger
limitation depending on the VBUS voltage droop.

BRANCH=smaug
BUG=chrome-os-partner:42045
TEST=Connect a Nexus 9 DCP charger to Smaug and see the input current
adjusted to 1650mA without brown-out, read back the value properly from
the AP:
$ ectool usbpdpower
Port 0: SNK Charger DCP 4958mV / 1650mA, max 5000mV / 1650mA / 8250mW
