gpu: nvgpu: move gp106 clk debugfs to linux

Move linux dependencies and CONFIG_DEBUG_FS to linux specific
code from common driver for gp106 clk debugfs. There is no
code change in functions moved from gp106/clk_gp106.c.

It uses nvgpu_os_linux_ops to add gp106 specific clk debugfs
ops. The linux specific part of nvgpu driver uses this op
to initialize gp106 clk debugfs.

As gv100 also uses gp106 clk debugfs ops, set up os ops for
gv100.
