dd739fcb03 gpu: nvgpu: Remove gk20a_dbg* functions 
Switch all logging to nvgpu_log*(). gk20a_dbg* macros are
intentionally left there because of use from other repositories.

Because the new functions do not work without a pointer to struct
gk20a, and piping it just for logging is excessive, some log messages
are deleted.

69252b3fb6 gpu: nvgpu: remove support for foreign sema syncfds 
Delete the proxy waiter for non-semaphore-backed syncfds in sema wait
path to simplify code, to remove dependencies to the sync framework (and
thus Linux) and to support upcoming refactorings. This feature has never
been used for actually foreign fences.
