[PULL 33/43] target/arm/kvm: Have kvm_arm_[get|put]_virtual_time take ARMCPU argument

[Peter Maydell]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

Unify the "kvm_arm.h" API: All functions related to ARM vCPUs
take a ARMCPU* argument. Use the CPU() QOM cast macro When
calling the generic vCPU API from "sysemu/kvm.h".
