clk: qcom: gcc-msm8998: Fix Alpha PLL type for all GPLLs
All of the GPLLs in the MSM8998 Global Clock Controller are Fabia PLLs and not generic alphas: this was producing bad effects over the entire clock tree of MSM8998, where any GPLL child clock was declaring a false clock rate, due to their parent also showing the same. The issue resides in the calculation of the clock rate for the specific Alpha PLL type, where Fabia has a different register layout; switching the MSM8998 GPLLs to the correct Alpha Fabia PLL type fixes the rate (calculation) reading. While at it, also make these PLLs fixed since their rate is supposed to *never* be changed while the system runs, as this would surely crash the entire SoC. Now all the children of all the PLLs are also complying with their specified clock table and system stability is improved.
