skylake: ACPI: Clean up pch.asl

Clean up the code in pch.asl:
- move all the C header includes into here instead of duplicated
in various ASL files included from here
- move the trap field definition into platform.asl with the method
- alphebetize the includes
- move gpio.asl include into pch.asl
- remove duplicate irqlinks.asl include from lpc.asl
