soc/intel/xeon_sp/acpi: Refactor Xeon-SP ASL file location

soc/intel/xeon_sp/acpi/*.asl are actually used only by SKX and CPX
platforms and not forward compatible to later SoC generations.
Move them to soc/intel/xeon_sp/acpi/gen1/ for clean maintenance.

TEST=Build and boot on intel/archercity CRB
