I've tested this patch by comparing GPFx_CON register values, as 
nothing seems to be currently using pins from the GPF1...GPF5 banks 
as external interrupts on TM2, the only board based on Exynos5433.
I changed sii8620 interrupt-parent temporarily to &gpf1 and GPF1_CON
got configured properly with the patch and improperly without 
the patch. I guess this can be considered as
