AGP resume was broken since we moved to the new init path,
because we never re-enabled AGP on these systems at resume time.

This patch just calls the AGP resume call which just does the reinit
at resume time like the old path did.

Since AGP is pretty much gpu independant I did it outside
the gpu specific code.

Generally this is done at post, but might not always be done
with softboot or for connectors on docking stations.

Could probably be done once when the driver loads/resumes
rather than on each mode set.

The Lenovo W500 laptop hangs inside an SMI on brightness changes,
I thought it just needed the VGA disable but it turned out to require
slightly more work, setting the MC locations up just like the IGP
chip requirements seems to make it all happy again and I can boot
and play with brightness.

We should probably just do this for all chips and give up the VRAM
at 0x0 idea, it never seems to buy us anything but pain.

Immediate readback seems faulty on some chips.  I
suspect it takes a while to get through the fifo
to the actual register backbone.  There's no need
to read it back, so, just write the driver's copy
of the register's value directly.

Should fix bug 24535 and possibly 24218

When we are evicting from VRAM->RAM we allocate the ttm object,
but we don't set the caching policy on it before blitting into it.
This means on AGP we end up blitting into cached pages, and
the CPU later flushes out on top of them. This was mostly seen as
font corruption.

The other question is why we don't evict VRAM->GTT in a lot of cases,
this would save us some cache transitions since a lot of objects
that are evicted from VRAM will probably end up being pulled back in
a few operations later, and evicting them to system memory involves
2 unnecessary cache transitions.

Limiting the pll output range is a good thing generally as
it limits the number of possible pll combinations for a given
frequency presumably to the ones that work best on each card.
That's why the limits are in the bios tables. However, certain
duallink DVI monitors seem to like pll combinations that would
be limited by this at least on pre-DCE 3.0 r6xx hardware.  This
might need to be adjusted per family or per clock range in the
future.

Since we register all radeon devices, and the arbiter only cares about

The problem boils down to the order when the bit11
of the texture size is or'ed to the original width.
In the end each mipmap level has the same width or
height because of that 11 bit is ored to the scaled
down lod with and thus blows up the size again to the
full size or more due to the power of two rounding
afterwards.

The attached patch changes this order so that the
texture sizes are computed correct. Also the on error
the yet missing inputs to the size computation are
printed which helped me to find out where it really breaks.
