[0/2] KVM: arm64: pKVM memory transitions cleanup

Message

In order to help resolve my own bikeshedding on the outstanding pKVM
patches [1], small deck of patches to polish up the existing memory
transitions. Mainly:

 - Rejig the layout of pkvm_mem_transition
 - Stop using out pointers to get at the 'completer' addr
 - Use better-fitting terminology (source/target) to describe the
   addresses involved in a memory transition

Applies to 6.1-rc2. Politely compile tested, and that's just about it.

  KVM: arm64: Clean out the odd handling of completer_addr
  KVM: arm64: Redefine pKVM memory transitions in terms of source/target
