linux/bitfield.h can be included as long as linux/kernel.h is included first, so change the order of the includes and drop the duplicate macro.

Currently version and revision fields are masked out of the MIDR so there can only be one set of jsons per CPU. In a later commit multiple revisions of Neoverse N2 json files will be provided.
The highest valid version of json files should be used, but to make this work the mapfile has to be reverse sorted on the CPUID field so that the highest is found first. It's possible, but error prone, to do this manually so instead add an explicit sort into jevents.py. If the CPUID is a string then the rows are string sorted rather than numerically.

Metrics will be published here [1] going forwards, but they have slightly different scale units. To allow autogenerated metrics to be added more easily, update the scale units to match.
The more detailed descriptions have also been taken and added to the common file.

The new metrics contain a fix for N2 r0p3 where CPU_CYCLES should not be subtracted from stalls for topdown metrics anymore. The current metrics assume that the fix should be applied anywhere where slots != 5, but this is only the case for V2 and not N2 r0p3.
Split the metrics into two versions for N2 r0p0 and N2 r0p3. V2 still shares the same metrics, but uses r0p3. Apart from some slight naming and grouping differences the new metrics are functionally the same as the existing ones. Any missing metrics were manually appended to the end of the auto generated file.
For the events, the new data includes descriptions that may have product specific details and new groupings that will be consistent with other products.
After generating the metrics from the telemetry repo [1], the following manual steps were performed:
* Change the hard coded slots in neoverse-n2r0p3-v2 to #slots so that it will work on both N2 and V2. For neoverse-n2r0p0, keep it hard coded so that the metrics will work on kernels which don't report slots.
* Append some metrics from the old N2/V2 data that aren't present in the telemetry data. These will possibly be added to the telemetry-solution repo at a later time:
l3d_cache_mpki, l3d_cache_miss_rate, branch_pki, ipc_rate, spec_ipc, retired_rate, wasted_rate, load_spec_rate, store_spec_rate, advanced_simd_spec_rate, float_point_spec_rate, branch_immed_spec_rate, branch_return_spec_rate, branch_indirect_spec_rate
