Explicitly enable ILB_SERIRQ function 1 in cfio_regs_pad_ilb_serirq_PCONF0.

Pad configuration for SERIRQ is not set to enable the SERIRQ function after a reset though strangely, it is on initial boot.

Rebooting from Linux, reset command in u-boot and even pushing the reset button on the development board all lead to the SERIRQ function being disabled (address 0xfed0c560 with value of 0x2003cc80).
