When setting the pin function for external interrupts, the driver used

By updating wrong register, the external interrupts for chosen GPIO
would not work at all and some other GPIO might be configured to wrong
value.

Platforms other than Exynos5433 should not be affected as eint_base
equals pctl_base in such case.

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
