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

[Michael Kelley]

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