Subject: [PATCH v2] perf: fix arm64 build error

I'm seeing the following build error on arm64:

In file included from util/event.c:3:0:
util/event.h:95:17: error: 'PERF_REGS_MAX' undeclared here (not in a function)
u64 cache_regs[PERF_REGS_MAX];
^

This patch adds a PERF_REGS_MAX definition for arm64.
