iio: SPDX headers for core + non device driver parts.

From: Jonathan Cameron <[email protected]>

There is a general movement towards ensuring all of the kernel source files have SPDX headers. I have previously expressed the view, that, like many cleanups it would be better to do these when otherwise touching the relevant part of the code, rather than creating noise throughout.

Time to change my mind on that, and push through adding these to IIO.

Even in the core code, I was less than entirely consistent with the existing license markings, so there are places where the file headers don't match with the MODULE_LICENSE macro.
There were also headers that gained default SPDX license markings that actually aren't quite correct given the related c files sometimes did have well stated licenses.

If someone has time to check my logic on the these that would be great.

For the drivers, my intent is to use random periods of boredom (I'm on some long haul flights in the near future) to see if I can plough through them. If anyone wants to get ahead of the game and do their own drivers that would be great. This is particularly true in the big octopus drivers that spread throughout the IIO directories and beyond. I'd love it if other people took those on.

If in doubt, don't do a given file or put out a clearly worded email to the list asking for help!
