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

This patch moves gpio_op.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 all methods present inside
common gpio_op.asl like GRXS, GTXS etc. are still there.
2) Verify no ACPI error seen while running 'dmesg` from console.
