There's already a condition in place which attempts to detect this, but
since we've begun to require a PMU subdev even on boards where we don't
load a custom FW, it's become inaccurate.
This will prevent unnecessarily running a periodic fan update thread on
GP100 and newer, where we don't yet override the default PMU FW.

The timestamp and the cb_list are mutually exclusive, the cb_list can
only be added to prior to being signaled (and once signaled we drain),
while the timestamp is only valid upon being signaled. Both the
timestamp and the cb_list are only valid while the fence is alive, and
as soon as no references are held can be replaced by the rcu_head.
By reusing the union for the timestamp, we squeeze the base dma_fence
struct to 64 bytes on x86-64.

Currently dma_fence_signal() tries to avoid the spinlock and only takes
it if absolutely required to walk the callback list. However, to allow
for some users to surreptitiously insert lazy signal callbacks that
do not depend on enabling the signaling mechanism around every fence,
we always need to notify the callbacks on signaling. As such, we will
always need to take the spinlock and dma_fence_signal() effectively
becomes a clone of dma_fence_signal_locked().
v2: Update the test_and_set_bit() before entering the spinlock.
v3: Drop the test_[and_set]_bit() before the spinlock, it's a caller
error so expected to be very unlikely.

Standard DRM panel drivers for several panels used by omapfb2 are now

drivers/video/fbdev/omap2/omapfb/displays, part of the deprecated omapfb2

disabled, and the DRM panel drivers are useless in that case, make the
