As recently pointed [1], using different object types for the KVM and
non-KVM scenarios was a bad idea: "In general different device types
should represent guest-visibly different objects, not just implementation
differences."
This series converts the base ICP class and the "simple" ICS class to
support KVM. This is done through the use of kvm_irqchip_in_kernel(),
which allows the compiler to optimize the KVM branches out when CONFIG_KVM
isn't set.
The removal of the KVM specific object types greatly simplifies the code.
Please comment.

xics: Explicitely call KVM ICP methods from the common code
xics: Handle KVM ICP reset from the common code
xics: Handle KVM ICP realize from the common code
spapr/irq: Use the base ICP class for KVM
xics: Drop the KVM ICP class
xics: Explicitely call KVM ICS methods from the common code
xics: Handle KVM ICS reset from the "simple" ICS code
xics: Handle KVM interrupt presentation from "simple" ICS code
spapr/irq: Use the "simple" ICS class for KVM
xics: Drop the KVM ICS class
