[PATCH v1 3/4] perf tools: Crete header files with register names

[German Gomez <german.gomez@arm.com>]

This patch adds C headers containing the names of the registers of all
architectures (that currently support registers in perf).

A followup patch will re-implement the function "perf_reg_name" using
this headers to display register names consistent with the achitecture
of the perf.data files.
