arm-cci PMU updates for 4.1

Hi Olof, Arnd,

Please can you pull the following ARM CCI PMU updates for 4.1? Suzuki has reworked parts of the existing driver so that it can be used on CPUs booting in non-secure mode (i.e. ARM64 systems) and also make it easier to port over to new IP, such as CCI-500.

It's coming via me as $ARM_PERF_GUY, but Nico has Acked the core driver (non-PMU) changes. Note that these have been in next for a bit, but I can drop the branch once you've pulled.

arm-cci: Fix CCI PMU event validation (2015-03-27 13:45:02 +0000)

----------------------------------------------------------------
CCI-400 PMU updates

This series reworks some of the CCI-400 PMU code so that it can be used on both ARM and ARM64-based systems, without the need to boot in secure mode on the latter. This paves the way for CCI-500 support in future.

----------------------------------------------------------------
Suzuki K. Poulose (6):
drivers: cci: reject groups spanning multiple HW PMUs
arm-cci: Rearrange code for splitting PMU vs driver code
arm-cci: Abstract the CCI400 PMU specific definitions
arm-cci: Get rid of secure transactions for PMU driver
arm-cci: Split the code for PMU vs driver support
arm-cci: Fix CCI PMU event validation

Merged now. The Kconfig merge was a bit messy since someone decided to sort the file, and Stephen will see that too (cc:d here).
