Douglas Anderson 2de0b42da2 brcmfmac: sdio: Disable auto-tuning around commands expected to fail 
There are certain cases, notably when transitioning between sleep and
active state, when Broadcom SDIO WiFi cards will produce errors on the
SDIO bus.  This is evident from the source code where you can see that
we try commands in a loop until we either get success or we've tried
too many times.  The comment in the code reinforces this by saying
"just one write attempt may fail"

Unfortunately these failures sometimes end up causing an "-EILSEQ"
back to the core which triggers a retuning of the SDIO card and that
blocks all traffic to the card until it's done.

Let's disable retuning around the commands we expect might fail.
