[PATCH v3 12/34] clk: cdce925: remove unnecessary long casts on return

[Bryan O'Donoghue]

Due to the old function signature of clk_ops->round_rate the cdce925
round_rate functions end up doing 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 extraneous cast from:

- cdce925_pll_round_rate
- cdce925_clk_round_rate
- cdce925_clk_y1_round_rate
