perf/arm-cmn: Refactor DTC PMU register access
Annoyingly, we're soon going to have to cope with PMU registers moving
about. This will mostly be straightforward, except for the hard-coding
of CMN_PMU_OFFSET for the DTC PMU registers. As a first step, refactor
those accessors to allow for encapsulating a variable offset without
making a big mess all over. As a bonus, we can repack the arm_cmn_dtc
structure to accommodate the new pointer without growing any larger,
since irq_friend only encodes a range of +/-3.
