All drivers that use dma-bufs have been moved to the updated locking
specification wherein dma-buf reservation is to be locked while
accessing the dmabuf internal data. Lock is removed. So lock
the resv object onwards while updating dmabuf private data
used for compression and buffer metadata.
With this, we can enable compression for all kernel versions that
was disabled earlier for v6.2+ kernels.

In case of process crash or forceful closure of the channels, userspace
may not release the VEID. In that case, creating further subcontexts
may not be possible.
Hence, when the channel is closed forcibly (linux), release the VEID on
closure of the last channel in the subcontext.
With this, normally on linux, channel close will not relase the VEID
However, on qnx it will release the VEID. So delete subcontext devctl
call on qnx will be nop in normal case hence changed the error print
and error return to success.
Also added check in the subcontext delete ioctl fn that all channels
are unbound before deleting the subcontext. This is to ensure that
channels don't refer to dangling subcontext pointer.

Additionally, fix numerous compilation issues due to the bit rotted

nvpmodel updates the devfreq frequency limits as per power requirements
for specific chip. Clock arbiter ignored these limits and set clock
to maximum supported frequency which may lead to leaking power and
over heating.
Add support to get the devfreq limits by registering PM_QOS notifiers.
Note that with this patch we enable CONFIG_GK20A_PM_QOS when PM_DEVFREQ
is enabled. So it will be enabled for all supported kernels (4.9, 4.14
kernels continue to support this. For 5.10+ kernels notifiers added in
this patch will be used. Thermal framework related notifiers for kernels
after 4.14 will not be registered as those use downstream interfaces
that are not available.)
We maintain devfreq min/max limits in the scale profile and update those
in the notifier calls. We use these limits to clamp the frequency in the
clock arbiter.
