bwn(4): replace siba_bwn(4) compatibility shims with the native bhnd(4) interface, and remove the legacy siba_bwn code.

Authored by landonf on Dec 17 2017, 2:48 AM.



This removes the shim interface that allowed bwn(4) to use either siba_bwn(4) or bhnd(4), replacing all siba_bwn(4) calls with their bhnd(4) bus equivalents.
