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

What does "soft reset" mean?

My apologies, this is misleading/incorrect. Rebooting from Linux,
reset command in u-boot and even pushing the reset button on the
development board all lead to this condition (address 0xfed0c560 with
value of 0x2003cc80). On first boot, address 0xfed0c560 has a value of
0x2003cc81 (SERIRQ function selected).
I'll update the commit message, add your reviewed-by and post a v2.
