Subject: soc/intel/common/block/acpi: Move pep.asl to acpigen

There is a use-case for generating the AML bytecode at runtime for the
Intel Power Engine device, which comes in a followup patch.

BUG=b:185437326
TEST=verified on google/brya and google/dratini by dumping SSDT and
verifying the PEPD device matches what was previously in the DSDT:
    Scope (\_SB.PCI0)
    {
        Device (PEPD)
        {
            Name (_HID, "INT33A1")
            Name (_CID, EisaId ("PNP0D80")
            Method (_DSM, 4, Serialized)
            {
                ToBuffer (Arg0, Local0)
                If ((Local0 == ToUUID ("c4eb40a0-6cd2-11e2-bcfd-0800200c9a66")))
                {
                    ToInteger (Arg2, Local1)
                    If ((Local1 == Zero))
