soc/intel/common/block/acpi: Factor out common platform.asl

This patch moves platform.asl into common block acpi directory to
avoid duplicating the same ASL code block across SoC directory.

TEST=Able to build and boot TGL, CNL and CML platform.
1) Dump and disassemble DSDT, verify _PIC method present inside
common platform.asl is still there.
2) Verify no ACPI error seen while running 'dmesg` from console.
