    ACPI: prevent ACPI quirk warning mass spamming in logs
    The following patch prevent this warning to be displayed again & again (eg:
    nine times on my NForce2 motherboard) and thus improve signal to noise
    ratio in logs.
    The ATI quirk below probably needs a similar "fix" but I don't have
    the hardware to test.
    Btw arch/x86_64/kernel/early-quirks.c::nvidia_bugs() would probably need to
    be synced (but I don't have an x86_64 NVidia motherboard to boot test it).
    Still it shows the usefullity of the recent x86 merge thread.
