    intel_idle: Add __init annotation to matchup_vm_state_with_baremetal()

    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)
