Terje Bergstrom d6ff5ef649 gpu: nvgpu: Disable trace_printk use by default ...

trace_printk() does an extra stringify operation before calling
do_trace_printk(). The string ends up unused. This has an impact
to kernel even if we never end up using trace_printk().

Disable use of trace_printk() and introduce a Kconfig option for
re-enabling it.
