With openpic(4) using active-low as the default polarity, reconfigure
the internal interrupt sources as active-high. The internal interrupt
sources are disabled when programmed as active-low.
Note that the internal interrupts have no sense bit like the external
interrupts. We program them as edge-triggered to make sure we write a
0 value to a reserved register. It does not in any way say anything
about the sense of internal interrupt.
