AMD fam10 ACPI: Use common fixed sleepstates.asl
SSFG was meant to be used as a mask to enable sleepstates _S1 thru _S4. However as a logical instead of bitwise 'and' operation was used, all the states were enabled if only one was marked available. Note that all boards incorrectly had SSFG == 0x0D that previously enabled ACPI S3 sleep state even when it was not available.
