Silence this warning by using min_t(). Since cur_size will never be

size_t and use min_t(size_t, [...]) here.

Without this, a bo may get created in the cpu-inaccessible vram.
Before the CP engines get setup, all copies are done via cpu memcpy.

This means that the cpu tries to read from inaccessible memory, fails,
and the radeon module proceeds to disable acceleration.

Doing this has no downsides, as the real VRAM size gets set as soon as the
CP engines get init.

This is a candidate for 3.14 fixes.

This is effectively a revert of 4573388c.

Forcing a display active when there is none causes problems with
dpm on some SI boards which results in improperly initialized
dpm state and boot failures on some boards.  As for the bug commit
4573388c tried to address, one can manually force the state to
high for better performance when using the card as a headless compute
node until a better fix is developed.

If we are not able to properly initialize one of the gpu
engines for buffer paging, we limit vram to the size of
the cpu visible aperture.  We generally either use the gfx
or dma engine to do this.  Clean up the size limiting code
to only adjust the size based on what ring is selected
for buffer paging rather than making assumptions about which
engine is selected for paging.
