Rafał Miłecki 25c1556663 b43: flush some writes on Broadcom MIPS SoCs
Access to PHY and radio registers is indirect on Broadcom hardware and
it seems that addressing on some MIPS SoCs may require flushing. So far
this problem was noticed on 0x4716 SoC only (marketing names: BCM4717,
BCM4718).

Rafał Miłecki d342b95dd7 b43: don't duplicate common PHY read/write ops
Most of the PHYs use the same way of accessing registers, so move that
code to the shared place. An exception is G-PHY which sometimes access
A-PHY regs and requires special handling.

Rafał Miłecki c2cb2c4cf1 b43: use one shared function for setting MAC frequency
By the way add few chipsets that were tracked with "wl" dumps.

Karl Beldan 675a0b049a mac80211: Use a cfg80211_chan_def in ieee80211_hw_conf_chan
Drivers that don't use chanctxes cannot perform VHT association because
they still use a "backward compatibility" pair of {ieee80211_channel,
nl80211_channel_type} in ieee80211_conf and ieee80211_local.
