KVM: arm64: Don't mark "struct page" accessed when making SPTE young
Don't mark pages/folios as accessed in the primary MMU when making a SPTE
young in KVM's secondary MMU, as doing so relies on
kvm_pfn_to_refcounted_page(), and generally speaking is unnecessary and
wasteful. KVM participates in page aging via mmu_notifiers, so there's no
need to push "accessed" updates to the primary MMU.
Dropping use of kvm_set_pfn_accessed() also paves the way for removing
kvm_pfn_to_refcounted_page() and all its users.
