[PATCH] staging: clocking-wizard: Contain macro argument in parenthesis

[Soren Brinkmann]

A macro doing some arithmetic to calculate a register offset, did not
contain an argument to the macro in parentheses, potentially leading to
unexpected results when using that macro with arithmetic expressions as
argument.
