[PATCH v2] ptp: ptp_clockmatrix: repair non-kernel-doc comment

Do not use "/**" to begin a comment that is not in kernel-doc format.

Prevents this docs build warning:

drivers/ptp/ptp_clockmatrix.c:1679: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
    * Maximum absolute value for write phase offset in picoseconds

Then remove the kernel-doc-like function parameter descriptions
since they don't add any useful info. (suggested by Jakub)
