[bhnd] Initial bhnd(4) SPROM/NVRAM support. This adds support for the NVRAM handling and the basic SPROM hardware used on siba(4) and bcma(4) devices, including: * SPROM directly attached to the PCI core, accessible via PCI configuration space. * SPROM attached to later ChipCommon cores. * SPROM variables vended from the parent SoC bus (e.g. via a directly-attached flash device). Additional improvements to the NVRAM/SPROM interface will be required, but this changeset stands alone as working checkpoint.

[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.
