KVM: arm64: Manage software step state at load/put
KVM takes over the guest's software step state machine if the VMM is
debugging the guest, but it does the save/restore fiddling for every
guest entry.
Note that the only constraint on host usage of software step is that the
guest's configuration remains visible to userspace via the ONE_REG
ioctls. So, we can cut down on the amount of fiddling by doing this at
load/put instead.
