arch/x86: provide common Intel ACPI hardware definitions

Browse Source 
In the ACPI specification the PM1 register locations are well
defined, but the sleep type values are hardware specific. That
said, the Intel chipsets have been consistent with the values
they use. Therefore, provide those hardware definitions as well
a helper function for translating the hardware values to the
more high level ACPI sleep values.
