[PATCH v2 08/34] clk: bcm2835: change bcm2835_pll_rate_from_divisors to return unsigned long

[Bryan O'Donoghue]

bcm2835_pll_rate_from_divisors() returns a value directly as the return
value to round_rate(). clk_ops->round_rate() has been changed to an
unsigned long so for the sake of completeness and neatness this patch
updates the helper function to return the same data-type.
