lynxpoint: Fix GPIO and PM base reservations

The kernel ACPI was not happy with the Add inside a
ResourceTemplate (or perhaps within the IO declaration)

Instead make a buffer of IO reservations and turn _CRS
into a method that updates the buffer depending on the
chipset type.

This adds an \ISLP() method that checks the chipset LPC
device ID to see if it is -LP or -H.

It also increases the PM base reservation to 256 bytes
and moves both GPIO and PM base to above 0x1000 on -LP
chipsets.
