skylake: ACPI: Remove itss.asl and cleanup irqlinks.asl
Move the itss.asl code that was exporting PIRQ routing control registers into irqlinks.asl and use the PCR access methods to find the appropriate address. At the same time clean up the code in irqlinks.asl to follow formatting rules. Also now that the GPIO code in itss.asl is unused the file can be removed.
