P1023 external IRQ[4:6, 11] are not pin out, but the interrupts are
utilized by the PCIe controllers.  As they are not exposed as pins we
need to set them as active-high (internal to the SoC these interrupts
are pulled down).

IRQs[0:3,7:10] are pulled up on the board so we have them set as
active-low.
