[PATCH 1/5] drivers/bus: Move Arm CCN PMU driver

[robin.murphy@arm.com (Robin Murphy)]

The arm-ccn driver is purely a perf driver for the CCN PMU, not a bus
driver in the sense of the other residents of drivers/bus/, so let's
move it to the appropriate place for SoC PMU drivers. Not to mention
moving the documentation accordingly as well.
