The address can refer to either physical memory or IO virtual memory.
If referring to IO virtual memory, there will always be an associated
physical memory address. Rename this variable to "iova" to clarify in
all cases that this is the IO virtual memory, which in the absence of
an IOMMU is identical to the physical address.

Drop use of the deprecated drmP.h header file.
For all touched files divide include files into blocks,
and sort them within the blocks.
Fix fallout.

The idea is that gem_prime_export is deprecated in favor of
obj_funcs.export. That's much easier to do if both have matching
function signatures.

This function allows mapping a GEM object into a virtual memory address
space, which makes it useful outside of the GEM code.
While at it, rename the function so it doesn't clash with the function
that implements the DRM_TEGRA_GEM_MMAP IOCTL.

If commands buffer claims a number of words that is higher than its BO can
fit, a kernel OOPS will be fired on the out-of-bounds BO access. This was
triggered by an opentegra Xorg driver that erroneously pushed too many
commands to the pushbuf.
The CDMA commands buffer address is 4 bytes aligned, so check its
alignment.
The maximum number of the CDMA gather fetches is 16383, add a check for
it.
Add a sanity check for the relocations in a same way.

When an IOMMU device is available on the platform bus, allocate an IOMMU
domain and attach the display controllers to it. The display controllers
can then scan out non-contiguous buffers by mapping them through the
IOMMU.

Tegra124 supports a block-linear mode in addition to the regular pitch
linear and tiled modes. Add support for these by moving the internal
representation into a structure rather than a simple flag.
