Odyssey is a 64 bit ARM based SoC with multiple performance monitor
units for various blocks.

This series of patches introduces support for uncore performance monitor
units (PMUs) on the Marvell Odyssey platform. The PMUs covered in this
series include the DDR PMU and LLC-TAD PMU.

v8->v9:
- Addressed the review comments.
- Added platform specific flag in DDR PMU driver instead of version
  as there is already a platform specific data.
