gpu: nvgpu: gp106: Reduce usage of os_linux.h

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()).
