On some AR955x/QCA953x boards, noise floor calibration
gets stuck and the cause is a hardware/BB issue. To fix
this, peak detect calibration in the HW is disabled
and is done in the driver instead. There a few differences
with the calibration routine for older chips like
AR9331.

b43 has a FIXME about locking in the mac80211 set-beacon-int callback for a long time.
As it turns out there actually is a tiny race window that could result in
a use-after-free bug of the 'current_beacon' memory.
Nobody ever reported this, so it probably never happened.
Fix this by adding a spin lock that protects the current_beacon access.
We must not be in atomic context while accessing hardware (due to SDIO),
so the beacon update bottom half has to clone the skb and release the lock
before writing it to hardware.
Let's all hope that this stops the troll who is trying to submit incorrect
fixes for this issue repeatedly.
And let's hope that I'm not a troll, too, who just hides even more evil code
in an even more complex attempt to fix the issue.

The nvram file can hold a key=value combination in which the value
may have spaces, ie. 'RAW1=80 02 fe ff'. The parsing functionality
did not deal with this so it gives an error message:
[621746.311635] brcmfmac: brcmf_nvram_handle_key
warning: ln=90:col=11: '=' expected, skip invalid key entry
because RAW1=80 is being considerd as key=value pair and it expects
'=' sign after '02' for next key=value pair. This entry can be
completely ignored as firmware does not need it.
