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).

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.

By the way add few chipsets that were tracked with "wl" dumps.

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.

It was not possible to guess the conditions from MMIO dumps. Take them
from brcmsmac code.

We've compared b43 with brcmsmac and took functions names from the
later.

Analog is switched on right after reading PHY version:
read16 0xfaafc3e0 -> 0xa801
phy_read(0x043b) -> 0x0000
phy_write(0x043b) <- 0x0000
Switched off after after killing radio:
>>> Switch Radio(OFF) end
phy_read(0x043c) -> 0x0000
phy_write(0x043c) <- 0x0007
phy_read(0x043b) -> 0x0000
phy_write(0x043b) <- 0x0007

LCN-PHY was found in 14e4:4727 card. It uses LCN/1 and 0x2064/1 radio.
