If ib initialization failed don't try to test ib as it will result
in an oops (accessing NULL ib buffer ptr).

In some rare case the wptr returned from the hw wasn't 0 and leaded
to trick r600_process_irq that their were irq to process. Add a
check to bail out if irq hasn't been initialized this will avoid
oops provoqued by the rare wptr != 0 on initialization.

most of radeon_legacy_atom_set_surface() is taken care
of in atombios_set_base(), so remove the duplicate
setup and move the remaining bits (DISP_MERGE setup and
FP2 sync) to atombios_crtc.c where they are used.

The first dword of PACKET3_3D_DRAW_IMMD maps to
SE_VTX_FMT so the vertex size is part of the draw
packet.
This patch fixes a possible case where you have a
command buffer that does not contain SE_VTX_FMT
register write, but does contain PACKET3_3D_DRAW_IMMD.

Use same common function to disable agp so we replace the GART
callback by the proper one when we do so. This fix oops if
radeon_agp_init report failure.
This patch also move radeon_agp_init out of *_mc_init for r600
& rv770 so that we can have a similar behavior than for previous
hw, ie if agp_init fails it will fallback to GPU GART and disable
AGP.

radeon KMS need a GART of at least 32M to properly work. This patch
check the AGP aperture size and disable if it's less than 32M. Note
than unlike non KMS path we don't staticaly allocate AGP memory so
we are not wasting memory not used by graphic processing.

It's not necessary to unpin buffer in fb destruction. pin/unpin
need to be balanced and we don't pin in fb creation. We pin when
an fb is associated to a crtc and unpin when the fb is disassociated
from the crtc.
Note:
Maybe we should take reference on fb in set_base callback so fb
doesn't disappear until it's unbind from ctrc.

It appears that attempting AUXCH DDC breaks the subsequent attempt
to do DDC over the i2c lines, so use the sink type to determine
if we should be doing AUXCH or i2c DDC.
