Log message:
vmm: Allow linux guests to use kvm-clock
In order to allow guests to use the pvclock that is already
implemented in vmm, expose a KVM signature with the neccessary feature
bits in the secondary hypervisor cpuid range. As there is only one
feature bit for both KVM_MSR_SYSTEM_TIME and KVM_MSR_WALL_CLOCK,
implement support for the latter.
While there, also add the KVM_FEATURE_NOP_IO_DELAY feature bit, as vmm
does not need io delays.
