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.

In clk_gp106 the Linux platform specific data is only referenced if
debugfs is being used. Thus only include the Linux OS stuff if debugfs
is enabled. This allows us to compile the rest of the clk code in non-
Linux kernel environments.
Also delete os_linux.h from xve_gp106.c since that header is unused
in the XVE code (and also do a minor cleanup by deleting the
pr_warn()).

Use the error code generated when the XVE clock change times out.
Before this the error code was being set and the while loop that
was polling the clock change status was broken out of. But the
error code was only used later on in the while loop.
Now just set the error code and only break from the loop later on
when that error code is actually checked.

nvgpu_log/info/warn/err() internally add a \n to the end of the message.
Hence, callers should not include a \n at the end of the message. Doing
so results in duplicate \n being printed, which ends up creating empty
log messages. Remove the duplicate \n from all err/warn messages.
