linux/debugfs.h was included in gk20a.h because of the debugfs entry bios_blob, which can be used for checking contents of VBIOS. That has never been used, so instead of abstracting it, this patch removes the feature altogether. Two files were using debugfs but did not #include <linux/debugfs.h>. They failed to build now that gk20a.h no longer #includes it, so added explit #include.
