Suzuki K Poulose 342c8a1d1d coresight: etm4x: Fix save/restore during cpu idle
The ETM state save/restore incorrectly reads/writes some of the 64bit
registers (e.g, address comparators, vmid/cid comparators etc.) using
32bit accesses. Ensure we use the appropriate width accessors for
the registers.
