SSFG was meant to be used as a mask to enable sleep states _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. State _S3 is now set conditionally if HAVE_ACPI_RESUME=y. For pi/hudson this had been fixed already preprocessor. Note that all boards had SSFG == 0x0D that previously enabled ACPI S3 sleep state even when it was not available. States _S1 and _S2 still appear enabled in ASL/AML but may not actually work. TEST: 'cat /sys/power/state' and notice choice 'mem' was removed from the list of available sleep states.
