dedede: Change PP3300_A PGOOD update method
We cannot read the ADCs in interrupt context, therefore we are changing
the method in which we determine the PP3300_A_PGOOD status. This commit
adds a ADC threshold interrupt for the PP3300_A PGOOD signal which
updates a variable in SRAM. This way, the chipset task can simply use
that variable for the PGOOD status instead of performing an ADC
conversion in interrupt context.
BUG=b:148169171
BRANCH=None
TEST=Build and flash waddledoo, verify that PP3300_A PGOOD is updated
correctly.
TEST=Verify that DUT does not panic while power sequencing
