bhnd(4): Implement backplane interrupt handling.
This adds bhnd(4) bus-level support for querying backplane interrupt vector routing, and delegating machine/bridge-specific interrupt handling to the concrete bhnd(4) driver implementation. On bhndb(4) bridged PCI devices, we provide the PCI/MSI interrupt directly to attached cores. On MIPS devices, we report a backplane interrupt count of 0, effectively disabling the bus-level interrupt assignment. This allows mips/broadcom to temporarily continue using hard-coded MIPS IRQs until bhnd_mips PIC support is implemented. Reviewed by: mizhka Approved by: adrian (mentor, implicit)
