First, the "kvm-no-adjvtime" and "kvm-steal-time" are only
available when KVM is available, so guard this block within
a 'kvm_enabled()' check. Since the "kvm-steal-time" property
is always available under KVM, directly set it.

Then, the "kvm-no-adjvtime" property is added to ARMCPU when
the ARM_FEATURE_GENERIC_TIMER feature is available. Rather than
checking whether the QOM property is present, directly check
the feature.

Finally, since we are sure the properties are available, we can
use &error_abort instead of NULL error. Replace:

  object_property_set_bool(..., PROPERTY, ..., &error_abort);

by:

  qdev_prop_set_bit(..., PROPERTY, ...);

which is a one-to-one replacement.
