ARM: S3C64XX: Provide for board-specific IRQs

Browse Source 
Set up some IRQ space to allocation to off-SoC interrupt controllers.
Default this to 16 IRQs. If individual boards require more than this
then they will need to modify this file so allocating a small number
helps reduce the number of modifications required.
