[PATCH] clk: not calculate new rate for protected clks

[PATCH] clk: not calculate new rate for protected clks

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

If the protect_count of the parent clk is not 0, we not calculate new
rates for parent. Otherwise, the common clk framework may configure
other child clks that is under using.
