AMD Kabini: fix issue 'S3 fails to suspend after wake up from USB keyboard'
Propagated from

http://review.coreboot.org/3374
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.
Both amd/olivehill and asrock/imb-a180 have been validated.
