I assume that all the users of this header file are imx6q syscon
clients.  In that case, this header belongs to mfd/syscon subsystem.

I have been told by people that it was a mistake to create
include/linux/fsl.  Each header in include/linux should go to
respective subsystem sub-directory.  For this particular case,
it should be include/linux/mfd or include/linux/mfd/syscon even
better, IMO.

Nit: why do we have a "!" there?
