Hi Jamie,

Well, the ARM11MPCore SCU counters are memory mapped and I have a feeling that
anything [counter-wise] outside the CPU core will likely be memory mapped in the
future.

I've had a go at using a platform_device instead of the struct pmu_irqs, I'll post
the changes for you to take a look at.

Thanks for that. Please take a look at the platform_device version and see what
you reckon.

Cheers,

Will
