KVM: arm64: Mark kvm_arm_init() and its unique descendants as __init

Browse Source 
Tag kvm_arm_init() and its unique helper as __init, and tag data that is
only ever modified under the kvm_arm_init() umbrella as read-only after
init.

Opportunistically name the boolean param in kvm_timer_hyp_init()'s
prototype to match its definition.
