Armin Wolf a089dad6f9 platform/x86: asus-nb-wmi: Ignore unknown event 0xCF 
[ Upstream commit e9fba20c29 ]

On the Asus X541UAK an unknown event 0xCF is emited when the charger
is plugged in. This is caused by the following AML code:

    If (ACPS ())
    {
        ACPF = One
        Local0 = 0x58
        If (ATKP)
        {
            ^^^^ATKD.IANE (0xCF)
        }
    }
    Else
    {
        ACPF = Zero
        Local0 = 0x57
    }

    Notify (AC0, 0x80) // Status Change
    If (ATKP)
    {
        ^^^^ATKD.IANE (Local0)
    }

    Sleep (0x64)
    PNOT ()
    Sleep (0x0A)
    NBAT (0x80)

Ignore the 0xCF event to silence the unknown event warning.
