    AMD Parmer: fix issue 'S3 fails to suspend after wake up from USB keyboard'
    
    This issue can be reproduced in Linux by the following steps:
    1) use pm-suspend to suspend.
    2) use USB keyboard to wake up.
    3) use pm-suspend to suspend. FAIL To SUSPEND.
    
    The cause of this issue is:
    USB devices use bit 11(0x0b) of GP0_STS represents S3 wake up event,
    but this bit is not clear after wake up. So OS thinks there is a
    wake up signal and wake up immediately.
    
    In this patch, I add AcpiGpe0Blk using MMIO access and write 1
    on bit 11. I have tested on Parmer.
