[PATCH v12 6/8] clk: qcom: cpu-8996: Add support to switch to alternate PLL

From: Rajendra Nayak Each of the CPU clusters on msm8996 are powered via a primary PLL and a secondary PLL. The primary PLL is what drives the CPU clk, except for times when we are reprogramming the PLL itself, when we temporarily switch to an alternate PLL. Use clock rate
