Subject: [PATCH v1] intel_idle: Add __init annotation to matchup_vm_state_with_baremetal()

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

The caller of (recently added) matchup_vm_state_with_baremetal() is an
__init function and it uses some __initdata data structures, so add the
__init annotation to it for consistency.

This addresses the following build warnings:

WARNING: modpost: vmlinux: section mismatch in reference: matchup_vm_state_with_baremetal+0x51 (section: .text) -> intel_idle_max_cstate_reached (section: .init.text)
WARNING: modpost: vmlinux: section mismatch in reference: matchup_vm_state_with_baremetal+0x62 (section: .text) -> cpuidle_state_table (section: .init.data)
WARNING: modpost: vmlinux: section mismatch in reference: matchup_vm_state_with_baremetal+0x79 (section: .text) -> icpu (section: .init.data)

Fixes: 0fac214bb75e ("intel_idle: Add a "Long HLT" C1 state for the VM guest mode")
