charge_ramp: Move ramp allowed / ilim callbacks to common code
The decision on whether to ramp (and how high) depends on the quirks of charger identification, so move the decision out of board, into the drivers that implement usb_charger. Also, rename CONFIG_CHARGE_RAMP to CONFIG_CHARGE_RAMP_SW, to better contrast with the existing CONFIG_CHARGE_RAMP_HW. BUG=None TEST=Manual on kevin, verify ramp occurs when port plugged into Z840 workstation.
