clk: qcom: Fix mmcc-8974's PLL configurations
We forgot to add the status bit for the PLLs and we were using
the wrong register and masks for configuration, leading to
unexpected PLL configurations. Fix this.
Fixes: d8b212014e69 (clk: qcom: Add support for MSM8974's multimedia clock controller (MMCC))
