cpu/arm7_common: Cleaned up IRQ code

Browse Source 
- Moved VIC.c to irq_arch.c for consistent naming scheme
- Removed unused functions IRQenabled, disableFIQ, restoreFIQ, enableFIQ
    - There is not header for those functions, so they *cannot* be used
    - These is obviously no user, as they *cannot* be used
    - There is absolutely no documentation what they would be used for
