This patchset adds support for the iommu, gpu and audio clocks on
the MSM8916 platforms.
Changes since v2 (https://lkml.org/lkml/2015/6/5/324)
* Dropped patch for read-only RCGs as it is not needed.
* Updated RCGs with shared branches patch and addressed various issues
pointed by Stephen.
* Rebased on clk-next.
Changes since v1
* Added a set of ops for read-only RCGs and RCGs with shared branches.
