We're giving up all attempts to keep cpu- and device byte ordering separate.
This silences sparse when compiled using
make C=2 CF="-D__CHECK_ENDIAN__"

This commit reworks device initialization so that we always enable the
FIFO at driver load, deferring SVGA enable until either first modeset
or fbdev enable.
This should always leave the fifo properly enabled for render- and
control nodes.
In addition,
*) We disable the use of VRAM when SVGA is not enabled.
*) We simplify PM support so that we only throw out resources on hibernate,
not on suspend, since the device keeps its state on suspend.

Contrary to the host-backed shader interface that has a per-context
name-space for shaders, the compat shader namespace was per client
(or rather, per file). Fix this so that the compat shader namespace is per
context, and at the same time, make command buffer managed context resource
management generic.

Don't use a per-master semaphore (ttm lock) for reservation protection, but
rather a per-device semaphore. This is needed since clients connecting using
render nodes aren't master aware.
The ttm lock used should probably be replaced with a reader-write semaphore
once the function down_xx_interruptible() is available.

When a context is first referenced in the command stream, make sure that all
scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that
all bound resources are put on the resource validate list.
This is needed for legacy emulation, since legacy user-space drivers will
typically not re-emit shader bindings. It also removes the requirement for
user-space drivers to re-emit render-target- and texture bindings.
Makes suspend and hibernate now also work with legacy user-space drivers on
guest-backed devices.
v2: Don't rebind on legacy devices.

Only scrub context bindings when a bound resource is destroyed, or when
the MOB backing the context is unbound.
