docs: add interrupts-target field to sp manifest
In order to support the ability to target a SPI interrupt to a
particular core, an impdef field "interrupts-target" has been added to
associate and interrupt id with an mpidr. The field is optional and if
not provided, existing SPMC behavior of routing to boot strap core is
maintained.
