clk: socfpga: remove redundant initialization of variable div

commit  d04a9d8be817ede06bb05d419acfe5f5bbf6115f from
https://github.com/altera-opensource/linux-socfpga.git

[upstream commit 52d1a8da

The variable div is being initialized with a value that is
never read and it is being updated later with a new value.  The
initialization is redundant and can be removed.
