Cover letter [PATCH v2 0/5] Add support for MSM8996 clock controllers

These patches add support for the global and multimedia clock controllers found on MSM8996 devices. The first patch allows us to implement a "power of two" divider of different widths with a table based divider. The second patch adds support for Alpha PLLs and the 3rd and 5th patches add support for the two clock controllers. The fourth patch is a new type of clock ops for the graphics clock that does some custom ping-pong between different PLLs when switching graphics frequencies.

Changes from v1:
* Added some missing clocks in gcc and mmcc drivers
* Updated PLL settings in mmcc
