arm-cci: Split the code for PMU vs driver support

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).
