ARM: S5P: Fix the platform external interrupt issues.
This patch does the following:
1. Corrects the common platform code for external interrupts for using the
VIC mask/unmask bits also.
2. Moves the common defines related to external interrupt for plat-s5p
to common files.
3. Based on the new common defines, corresponding changes are made in the
affected platforms (S5P6440, S5P6442 and S5PC100).
