[bwn] [bhnd] initial support for using bhnd for if_bwn devices.
This is an initial work in progress to use the replacement bhnd
bus code for devices which support it.
* Add manpage updates for bhnd, bhndb, siba
* Add kernel options for bhnd, bhndbus, etc
* Add initial support in if_bwn_pci / if_bwn_mac for using bhnd
as the bus transport for suppoted NICs
* if_bwn_pci will eventually be the PCI bus glue to interface to bwn,
which will use the right backend bus to attach to, versus direct
nexus/bhnd attachments (as found in embedded broadcom devices.)
The PCI glue defaults to probing at a lower level than the bwn glue,
so bwn should still attach as per normal without a boot time tunable set.
It's also not fully fleshed out - the bwn probe/attach code needs to be
broken out into platform and bus specific things (just like ath, ath_pci,
ath_ahb) before we can shift the driver over to using this.
Tested:
* BCM4311, STA mode
* BCM4312, STA mode
