This changes the powerpc perf_counter back-end to use unsigned long types for hardware register values and for the value/mask pairs used in checking whether a given set of events fit within the hardware constraints. This is in preparation for adding support for the PMU on some 32-bit powerpc processors. On 32-bit processors the hardware registers are only 32 bits wide, and the PMU structure is generally simpler, so 32 bits should be ample for expressing the hardware constraints. On 64-bit processors, unsigned long is 64 bits wide, so using unsigned long vs. u64 (unsigned long long) makes no actual difference. This makes some other very minor changes: adjusting whitespace to line things up in initialized structures, and simplifying some code in hw_perf_disable().
