HT-PHY was found only on BCM4331 which is a BCMA-based chipset. This is
reallly unlikely we will ever see HT-PHY on SSB thus make the whole code
BCMA specific. This will allow us to call various BCMA-specific
functions directly (without extra checks).

The function brcmf_proto_hdrpush() increases the header space and
fills in the protocol header fields. One field is the data offset
which is currently fixed to zero meaning the data follows right
after the header. The parameter is added to determine the actual
start of data. This will be used for firmware signalling.

With "mac80211/minstrel_ht: add support for using CCK rates"
minstrel_ht selects legacy CCK rates as viable rates for
outgoing frames which might be sent as part of an A-MPDU
[IEEE80211_TX_CTL_AMPDU is set].
This behavior triggered the following WARN_ON in the driver:
> WARNING: at carl9170/tx.c:995 carl9170_op_tx+0x1dd/0x6fd
The driver assumed that the rate control algorithm made a
mistake and dropped the frame.
This patch removes the noisy warning altogether and allows
said A-MPDU frames with CCK sample and/or fallback rates to
be transmitted seamlessly.
