gpu: nvgpu: Put debugfs dependencies inside #ifdef

Put all debugfs dependencies inside #ifdef CONFIG_DEBUG_FS. This
includes some functions in allocators that were used only for
debugging.

Remove include of linux/debugfs.h on files that do not deal with
debugfs.

linux/debugfs.h implicitly included linux/fs.h, which we relied on.
Add explicit include of linux/fs.h for all files where this is the
case.
