ACPI: allow a native cpuidle driver to displace ACPI
The ACPI driver would fail probe when it found that
another driver had previously registered with cpuidle.
But this is a natural situation, as a native hardware
cpuidle driver should be able to bind instead of ACPI,
and the ACPI processor driver should be able to handle
yielding control of C-states while still handling
P-states and T-states.
Add a KERN_DEBUG line showing when acpi_idle
does successfully register.
