clk: bcm-2835: Remove rounding up the dividers
The driver, once it found a divider, tries to round it up by increasing the least significant bit of the fractional part by one when the round_up argument is set and there's a remainder. However, since it increases the divider it will actually reduce the clock rate below what we were asking for, leading to issues with clk_set_min_rate() that will complain that our rounded clock rate is below the minimum of the rate. Since the dividers are fairly precise already, let's remove that part so that we can have clk_set_min_rate() working. This is effectively a revert of 9c95b32c ("clk: bcm2835: add a round up ability to the clock divisor").
