Kernel: Add reserve_interrupt_handlers API

Browse source 
MSI(x) interrupts need to reserve IRQs so that it can be programmed by
the device. Add an API to reserve contiguous ranges of interrupt
handlers so that it can used by PCI devices that use MSI(x) mechanism.

This API needs to be implemented by aarch64 architecture.
