[PATCH AUTOSEL 6.3 07/17] arm64/hyperv: Use CPUHP_AP_HYPERV_ONLINE state to fix CPU online sequencing

[Sasha Levin]

From: Michael Kelley <mikelley at microsoft.com>

[ Upstream commit 52ae076c3a9b366b6fa9f7c7e67aed8b28716ed9 ]

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.
