arm64/arch_timer: include <linux/percpu.h>

arch_timer.h includes linux/smp.h since the commit:

  6acc71ccac7187fc ("arm64: arch_timer: Allows a CPU-specific erratum to only affect a subset of CPUs")

It was included to use DEFINE_PER_CPU(), etc. But It should have
included <linux/percpu.h> rather than <linux/smp.h>. It worked because
smp.h includes percpu.h.

The next commit will remove percpu.h from smp.h and it will break this
usage.

Explicitly include percpu.h and remove smp.h
