Subject: [PATCH v2 0/9] SDM630/660 GCC/MMCC/GPUCC clock controllers

This patch series brings up the MultiMedia Clock Controller (MMCC)
and the GPU Clock Controller (GPUCC), plus includes some fixes for
the SDM660 GCC, which are necessary for correct functionality of
the clocks from the two new drivers, without causing lockups.

There is also a change in the RCG2 GFX3D, which generalizes the
gfx3d pingpong handling functions, in order to be able to reuse
them for more than just one specific SoC (MSM8996), bringing no
functional changes to the aforementioned SoC, which got a MMCC
driver gfx3d clock fix for the generalization... obviously.

This patch series has been tested against the following devices:
 - Sony Xperia XA2 Ultra (SDM630 Nile Discovery)
 - Sony Xperia 10        (SDM630 Ganges Kirin)
 - Sony Xperia 10 Plus   (SDM636 Ganges Mermaid)
