Currently we have the cpuidle_device field in the acpi_processor_power

This adds a dependency between processor.h and cpuidle.h
Although it is not a real problem, removing this dependency has the benefit of
separating a bit more the cpuidle code from the rest of the acpi code.

Use r12 to pass the hypercall number to the hypervisor.
We need a register to pass the hypercall number because we might not
know it at compile time and HVC only takes an immediate argument.
Among the available registers r12 seems to be the best choice because it
is defined as intra-procedure
