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.
