[PATCH 1/5] staging: remove unused methods

[Andy Shevchenko <andy.shevchenko@gmail.com>]

This is rebased version of the patch [1] which was mysteriously not
pushed anywhere but acked.

Here are two methods to convert hex value to binary format. These
certain methods aren't used anywhere in kernel.
