Add smn(4) driver for AMD System Management Network

AMD Family 17h CPUs have an internal network used to communicate between
the host CPU and the PSP and SMU coprocessors.  It exposes a simple
32-bit register space.

amdtemp(4): Add support for Family 17h temperature sensor

The sensor value is formatted similarly to previous models (same
bitfield sizes, same units), but must be read off of the internal
System Management Network (SMN) from the System Management Unit (SMU)
co-processor.

amdtemp(4): Do not probe not matching hostbridges

Some systems have hostbs that do not match our PCI device id criteria.
Detect and ignore these devices in probe.

amdsmn(4): Do not probe not matching hostbridges

Similar to r323195, but for amdsmn(4) driver (which borrowed some design).

Ignore hostbs that do not match our PCI device id criteria.
