[PATCH] arch/arm: Fix missing define for ARM_PMU_DEVICE_CPU

[Peter Huewe]

From: Peter Huewe <peterhuewe at gmx.de>

This patch adds a define for ARM_PMU_DEVICE_CPU which seemed to be
missing/undefined and caused some build failures [1-4].

I defined ARM_PMU_DEVICE_CPU = -1 as stated in
Documentation/driver_model/platform.txt to indicate there is only one.
I'm _not_ sure if this is correct, but due to the static nature of the
define I assume it is.
