Currently, debugfs functions are using symbolic macros as permission
bits, but checkpatch reinforces permission bits in the octal form, as
they are more readable and easier to understand [1]. Moreover, using
the symbolic macro S_IFREG is redundant.

Therefore, use octal permission bits in all debugfs functions.
