[PATCH] ARM: tegra: register PMU IRQs with PMU framework

[Will Deacon]

The Tegra Harmony board contains a dual-core Cortex-A9 and can therefore
make use of the hardware performance counters on the CPU.

This patch fixes a typo in the PMU IRQ definitions and registers the
interrupts as a platform_device with the PMU framework.

This patch was taken against 2.6.36-rc1 but has not even been compile-tested
because of the following errors:

arch/arm/mach-tegra/board-harmony.c: In function 'tegra_harmony_fixup':
arch/arm/mach-tegra/board-harmony.c:116: error: 'struct membank' has no member named 'node'
arch/arm/mach-tegra/board-harmony.c:116: error: implicit declaration of function 'PHYS_TO_NID'
arch/arm/mach-tegra/board-harmony.c:119: error: 'struct membank' has no member named 'node'
