[PATCH v2 2/2] arm64/hyperv: Use CPUHP_AP_HYPERV_ONLINE state to fix CPU online sequencing

State CPUHP_AP_HYPERV_ONLINE has been introduced to correctly sequence the
initialization of hyperv_pcpu_input_arg. Use this new state for Hyper-V
initialization so that hyperv_pcpu_input_arg is allocated early enough.
