This patch separates the PMU driver code from the low level
CCI driver code and enables the PMU driver for ARM64.

Introduces config options for both.

ARM_CCI400_PORT_CTRL - controls the low level driver code for
CCI400 ports.
ARM_CCI400_PMU - controls the PMU driver code
ARM_CCI400_COMMON - Common defintions for CCI400

This patch also changes:
ARM_CCI - common code for probing the CCI devices. This can be
used for adding support for newer CCI versions(e.g, CCI-500).

Changes since V2:
- Make ARM_CCI400_PMU default y (Suggested-by: Sudeep Holla)
Changes since V1 (Suggestions-by: Nicolas Pitre):
- Renames
CONFIG_ARM_CCI400_MCPM => CONFIG_ARM_CCI400_PORT_CTRL
CCI400_MCPM_PORTS_DATA => CCI400_PORTS_DATA
- Select ARM_CCI400_COMMON for ARM_CCI400_PORT_CTRL
- Better documentation in the git commit log about the ARM_CCI config.
