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.
