bhnd(4): implement MIPS and PCI(e) interrupt support

On BHND MIPS SoCs, this replaces the use of hard-coded MIPS IRQ#s in the
common bhnd(4) core drivers; we now register an INTRNG child PIC that
handles routing of backplane interrupt vectors via the MIPS core.

On BHND PCI devices, backplane interrupt vectors are now routed to the
PCI/PCIe host bridge core when bus_setup_intr() is called, where they are
dispatched by the PCI core via a host interrupt (e.g. INTx/MSI).

The bhndb(4) bridge driver tracks registered interrupt handlers for the
bridged bhnd(4) devices and manages backplane interrupt routing, while
delegating actual bus interrupt setup/teardown to the parent bus on behalf
of the bridged cores.

[bhnd] Implement pass-through resource management for ChipCommon.

This patchset adds support to bhnd_chipc for sharing SYS_RES_MEMORY
resources with its children, allowing us to hang devices off of
bhnd_chipc that rely on access to a subset of the device register space
that bhnd_chipc itself must also allocate.

We could avoid most of this heavy lifting if RF_SHAREABLE+SYS_RES_MEMORY
wasn't limited to use with allocations at the same size/offset.

As a work-around, I implemented something similar to vga_pci.c, which
implements similar reference counting of of PCI BAR resources for its
children.

With these changes, chipc will use reference counting of SYS_RES_MEMORY
allocation/activation requests, to decide when to allocate/activate/
deactivate/release resources from the parent bhnd(4) bus.

The requesting child device is allocated a new resource from chipc's
rman, pointing to (possibly a subregion of) the refcounted bhnd resources
allocated by chipc.

Other resource types are just passed directly to the parent bhnd bus;
RF_SHAREABLE works just fine with IRQs.

I also lifted the SPROM device code out into a common driver, since this
now allows me to hang simple subclasses off of a common driver off of both
bhndb_pci and bhnd_chipc.

Tested:

* (landonf) Tested against BCM4331 and BCM4312, confirmed that SPROM still
attaches and can be queried.
