This patch series fixes some issues with the MSM8998 clocks and, in
particular, brings a very important fix to the GCC PLLs.

These fixes are enhancing this SoC's stability and also makes it
possible to eventually enable the Adreno GPU (with proper clock
scaling) and other components.

This patch series was tested on:
- Sony Xperia XZ Premium (MSM8998)
- F(x)Tec Pro1 (MSM8998)
