power: Add CONFIG_* option for PROCHOT polarity.
The common x86 chipset code assumed that CPU_PROCHOT was active high,
however on some boards it's actually active low. This commit simply
adds a CONFIG_* option, CONFIG_CPU_PROCHOT_IS_ACTIVE_LOW, and inverts
the places where the signal is used.
BUG=b:109882953
BRANCH=poppy
TEST=Enable on nocturne; flash, verify that CPU_PROCHOT is not asserted
by default.
