mainboards: align on using ACPI_Sx definitions
The mainboard_smi_sleep() function takes ACPI sleep values of the form S3=3, S4=4, S5=5, etc. All the chipsets ensure that whatever hardware PM1 control register values are used the interface to the mainboard is the same. Move all the SMI handlers in the mainboard directory to not open code the literal values 3 and 5 for ACPI_S3 and ACPI_S5. There were a few notable exceptions where the code was attempting to use the hardware values and not the common translated values. The few users of SLEEP_STATE_X were updated to align with ACPI_SX as those defines are already equal. The removal of SLEEP_STATE_X defines is forthcoming in a subsequent patch.
