To configure the virtual PMUv3 overflow interrupt number, we use the
vcpu kvm_device ioctl, encapsulating the KVM_ARM_VCPU_PMU_V3_IRQ
attribute within the KVM_ARM_VCPU_PMU_V3_CTRL group.
After configuring the PMUv3, call the vcpu ioctl with attribute
KVM_ARM_VCPU_PMU_V3_INIT to initialize the PMUv3.

In some cases it needs to get/set attributes specific to a vcpu and so
needs something else than ONE_REG.
Let's copy the KVM_DEVICE approach, and define the respective ioctls
for the vcpu file descriptor.
