Subject: [PATCH v3 3/3] clk: qcom: gcc-sdm845: add sdm670 global clock data

The Snapdragon 670 adds and removes some clocks, adds new frequencies, and
adds a new GPLL (Global Phase-Locked Loop) in reference to SDM845, while
also removing some GDSCs. Despite these differences, there are many
similarities with SDM670. Add data for SDM670 in the driver for SDM845 to
reuse the most of the clock data.

Advantages and disadvantages of this approach:
+ maintenance applies to both sdm670 and sdm845 by default
+ less duplicate code (clocks) means smaller distro/pre-built kernels
with all drivers enabled
- clocks for both SoC's must be compiled if the user wants clocks for one
specific SoC (both or none)
- additional testing needed for sdm845 devices
