KVM: arm64: pkvm: Save host FPMR in host cpu context
Protected KVM stores most of the host's system register state in
kvm_host_data::host_ctxt, which is an instance of struct
kvm_cpu_context. As kvm_cpu_context::sys_regs[] has a slot for FPMR, we
can store the host's FPMR there.
Do so, and remove kvm_host_data::fpmr.
