The debugfs support for the xpcs registers did not properly use the
specified mmd (xpcs_mmd entry) which resulted in the default mmd
value always being used. Update the debugfs support to generate the
proper mmd register value.

The initial change from sscanf to kstrtouint broke backward
compatbility by using a base of "0" in the kstrtouint call.
This allowed for entering decimal, hexadecimal or octal as
input where previously the sscanf always interpreted the input
as hexadecimal. Additionally, -EIO was returned on error prior
to this change and now it is whatever the error value that is
returned by kstrtouint.
Change the base value of the kstrtouint from 0 to 16 and return
-EIO on error.

Checkpatch issued a warning preferring to use kstrto<type> when
using a single variable sscanf. Change the sscanf invocation to
a kstrtouint call.
