SPARC BSPs: implemented shared-irq using libbsp/shared layer
The implementation use IRQ number instead of vector number since
some IRQs does not have a unique vector, for example the extended
interrupts all enter the same trap vector entry.
Added support for the LEON3 extended interrupt controller when using
the shared IRQ layer.
ERC32 patches untested.
