Define the wakeup uart pin-mux for completeness. This allows the
device tree usage in bootloader and firmwares that can configure the
same appropriately.

If you like to consider alias for wkup_uart0 for this board ,

Just to align with other boards for this SOC family.  I understand 
wkup_uart0 is not being used.

Vignesh,
could you squash this locally OR if you like, I can post a v2:
