For Moorestown at least we may not have stolen RAM with which to back the
initial framebuffer. Allow a GEM backing.
At this point we should have all the bits in place needed to make it work once
it has been debugged.

There are two chunks of code we need to do this. The first one is the code
to insert and remove the pages from the GART, the second is the code to build
page table lists from the GEM object. Surprisingly this latter one doesn't seem
to have a nice GEM helper.
While we are at it we can begin dismantling the semi redundant struct pg,
and finish pruning out the old now unused gtt code as well as the last bits
of helper glue from the old driver base.

This puts in place the infrastructure for GEM allocators. Our implementation
is fairly simplistic at this point and we don't deal with things like
evicting objects from the GART to make space, nor compaction.
We extent our gtt_range struct to include a GEM object and that allows GEM
to do all the handle management and most of the memory mapping work for us.
This patch also doesn't load GEM pages into the GART so the GEM side isn't
very useful. Before we can do that a fair bit of work is needed reworking the
internal GTT code.

At the moment we don't do any page backing for the GTT so only the stolen
area pages will actually work. That is fine for our initial framebuffer and
a bit of testing but will need resolution (including alternate mmap methods
and the like for s/g areas) eventually.
Rather than use some of the overcomplex stuff in the DRM we use the existing
Linux resource allocators to hand out framebuffers and the like. This also has
the nice result that /proc/iomem shows the allocations.

stli_brdstats is defined as global variable. After de-BKL-ization in
the patch b4eda9cb48 an access to the variable is not serialized
anymore. This leads to the race window between the check and the use
in stli_getbrdstats():
if (copy_from_user(&stli_brdstats, bp, sizeof(combrd_t)))
return -EFAULT;
if (stli_brdstats.brd >= STL_MAXBRDS) <<<
return -ENODEV;
brdp = stli_brds[stli_brdstats.brd]; <<<
If one process calls COM_GETBRDSTATS ioctl() with sane .brd, second
process calls COM_GETBRDSTATS ioctl() with invalid .brd, and the
second process' copy_from_user() executes exactly between the check and
stli_brds[] indexation of the first process, then the first process gets
contents of memory at *stli_brds[stli_brdstats.brd] address. Also
the resulting .nrpanels field may be too big, in this case
stli_brdstats.panels array overflows.
