clk: socfpga: remove redundant initialization of variable div

commit  f14c0a775f57b5b086905b5ac405b393e1d01c62 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.
