icelake: Allow power good methods to be overidden

Jasperlake uses the same chipset driver as Icelake and the dedede
reference design does not have a distinct pins for a couple of the power
good signals. In order to accommodate this, this CL allows some of the
power good signals to be overidden by a board specific implementation.
These power good signals are PG_EC_DSW_PWROK and PG_ALL_SYS_PWRGD.
