clk: qcom: clock-pll: Remove no_prepared_reconfig optimization check



Previously, we were allowing a prepared PLL to support
a requested rate if it was already at that rate, even
with the no_prepared_reconfig flag set. This does not
account for downstream clock elements that may still
want to be able to select a different source, and does
not provide much benefit in terms of optimization anyway.
It is easier to design clock drivers without this
optimization in mind.
