Bug 1587090
Bug 200050711
PMU dmem start address is unaligned.
Allocator allocates aligned length amount of memory
But address alloced is nto checked to be aligned, but
free checks for alignment of addresses before free.
For dmem case, frees never actually happened. This fix
ensures addresses are aligned.

Remove support for gk20a sparse textures. We're using implementation
from user space, so gk20a code is never invoked.
Also removes ref_cnt for PTEs, so we never free PTEs when unmapping
pages, but only at VM delete time.

Channel update callback for a channel that has no more cde jobs signals
that a cde context is free. Spurious channel updates may still happen
from at least nonstalling semaphore wait interrupts. Instead of scary
WARNs, use only gk20a_dbg_info() for info prints in these harmless
situations, and double check that only the first update starts a deleter
work for temporary contexts.

Fix gk20a module removal so that the driver can be correctly removed
when built as a module (CONFIG_GK20A=m). Reinsertion correctly will need
more missing deinit calls, which are not yet implemented.
This change has no effect yet on any builds since the module is built in
by the defconfig.
- don't free threaded irqs that are bound to the device
- destroy cde if it is enabled
- remove all debugfs entries recursively generated directly and by cde,
pmu, clk etc.
- free secure buffer if it exists
- remove pm_runtime_put, since it doesn't have a pairing get
- pm_runtime defines proper function stubs if it is not enabled, so
remove ifdefs and query pm_runtime_enabled()
- null and free gk20a only after all deinit has been done

Wait for possible temp context deletion to finish properly before
passing contexts around later, to prevent situations where the context
deleter scheduling would have been completed, but running it would not,
and a new one could have been scheduled again. When finished, schedule
the deleter before freeing the context back to use to prevent races.
Warn in impossible situations when these double deletions would happen.

Rescheduling the temp context deleter when it is not immediately
possible is not necessary, and complicates things. Don't do it.
The context would anyway be used later when its time comes in the free
list, and the deletion would then be retried.
This simplifies canceling the works when shutting down or going into
suspend, since re-canceling the possibly rescheduled work is not needed.
Releasing the app mutex is still necessary when deleting the whole cde.

use, to prevent re-scheduling when the same context would be quickly
re-used and finished twice or more in a row before deletion.
