mb/google/brox: Handle GPI_INT pin lower to GPI_WAKE
In case where PAD_CFG_GPI_INT() is initialized with a pin value
lower to PAD_CFG_GPI_IRQ_WAKE() for same GPIO community
the set_ioapic_used() is only called for the PAD_CFG_GPI_IRQ_WAKE() pin.
Due to this the IRQ associated with PAD_CFG_GPI_INT() is found free by
find_free_unique_irq() during IRQ assignment and assigned to other pins
which causes IRQ conflicts
BUG=b:322984217
BRANCH=None
TEST=Boot test on brox, check if correct IRQ assigned to EC
