If userspace (plymouth in this case) asks for a deeper depth,
refuse it as well due to lack of resizing.

This fixes an issue since < 32MB cards went to 8bpp and plymouth
crashes on startup.

With the current DRM code, an output that has been powered off
from userspace will automatically power back on when resuming
from suspend. This patch fixes this behaviour.

Tested only with the Intel i915 driver on an Intel GM45 Express

R300 family will hard lockup if host path read cache flush is
done through MMIO to HOST_PATH_CNTL. But scheduling same flush
through ring seems harmless. This patch remove the hdp_flush
callback and add a flush after each fence emission which means
a flush after each IB schedule. Thus we should have same behavior
without the hard lockup.

Tested on R100,R200,R300,R400,R500,R600,R700 family.

drm_pci_alloc() has input of address mask for setting pci dma
mask on the device, which should be properly setup by drm driver.
And leave it as a param for drm_pci_alloc() would cause confusion
or mistake would corrupt the correct dma mask setting, as seen on
intel hw which set wrong dma mask for hw status page. So remove
it from drm_pci_alloc() function.
