dedede: Override power_signal_get_level()
The dedede EC's don't have GPIOs for some of the signals used for power
sequencing but instead have other logic. The common chipset driver
assumes that all these signals are either GPIOs or eSPI virtual wires
therefore these signals were not being updated correctly for dedede.
This commit adds an override for power_signal_get_level() in order to
get the correct values for the signals from the baseboard specific code.
BUG=b:148169171
BRANCH=None
TEST=Build and flash waddledoo, verify that DUT can boot to S0.
