Subject: [PATCH 22/33] clk: sirf: remove unnecessary long cast on return

Due to the old function signature of clk_ops->round_rate
pll_clk_round_rate does a cast of an internal unsigned long
to a long. After updating clk_ops->round_rate() to be an unsigned long
though the cast isn't necessary. Remove the cast now.
