The current compile-time check for inversed IENB/CNTL does not
work in multiplatform boots: as soon as versatile is included
in the build, the IENB/CNTL is switched and breaks graphics.
Convert this to a runtime switch.

Rename dma_*_writecombine() to dma_*_wc(), so that the naming
is coherent across the various write-combining APIs. Keep the
old names for compatibility for a while, these can be removed
at a later time. A guard is left to enable backporting of the
rename, and later remove of the old mapping defines seemlessly.
Build tested successfully with allmodconfig.
The following Coccinelle SmPL patch was used for this simple
transformation:
@ rename_dma_alloc_writecombine @
expression dev, size, dma_addr, gfp;
@@
-dma_alloc_writecombine(dev, size, dma_addr, gfp)
+dma_alloc_wc(dev, size, dma_addr, gfp)
@ rename_dma_free_writecombine @
expression dev, size, cpu_addr, dma_addr;
@@
-dma_free_writecombine(dev, size, cpu_addr, dma_addr)
+dma_free_wc(dev, size, cpu_addr, dma_addr)
@ rename_dma_mmap_writecombine @
expression dev, vma, cpu_addr, dma_addr, size;
@@
-dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size)
+dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size)
We also keep the old names as compatibility helpers, and
guard against their definition to make backporting easier.

This patch add a missing check on the return value of devm_kzalloc,
which would cause a NULL pointer dereference in a OOM situation.

The DT-based panel capabilities selection was picking up
a subset of available modes based on hardware configuration.
This was wrong, as the capabilities describe available
memory models and adapt the display controller to them
that the RGB output is wired up correctly (as in: R and
B components are not swapped).
This patch fixes it by removing the unnecessary limitation.

If the device-tree specifies a max-memory-bandwidth property then the
CLCD driver uses that to calculate the bits-per-pixel supported,
however, this calculation is faulty for two reasons.
1. It doesn't ensure that the result is a sane value, i.e. a power of 2
and <= 32 as the rest of the code assumes.
2. It uses the displayed resolution and calculates the average bandwidth
across the whole frame. It should instead calculate the peak
bandwidth based on the pixel clock.
This patch fixes both the above.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.
Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.
No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.
