integration/soc_core: rework interrupt assignation/reservation

The CPUs can now reserve specific interrupts with reserved_interrupts property.
User can still define interrupts in SoCCore.interrupt_map (old way) or use
add_interrupt method. Interrupts specific to SoCCore internal modules are
allocated automatically on the remaining free interrupt ids.

Priority for the interrupts allocation:
- 1) CPU reserved interrupts.
- 2) User interrupts.
- 3) SoCCore interrupts.
