clk: qcom: clk-alpha-pll: Update the PLL support for cal_l

Recent QCOM PLLs require the CAL_L field to be programmed according to
specific hardware recommendations, rather than using the legacy default
value of 0x44. Hardcoding this value can lead to suboptimal or incorrect
behavior on newer platforms.

To address this, introduce a `cal_l` field in the PLL configuration
structure, allowing CAL_L to be set explicitly based on platform
requirements. This improves flexibility and ensures correct PLL
initialization across different hardware variants.
