The registers for ARM and ARM64 are enumerated using two enums that have
the same name. In order to be able to import both headers, the name of
one can be replaced using the C preprocessor like so:

  #define perf_event_arm_regs perf_event_arm64_regs
  #include <asm/perf_regs.h>
  #undef perf_event_arm_regs

This patch updates all imports of ARM64's perf_regs.h in order to
prevent the naming collision.
