Dynamically generate PNP0C02 mainboard resources in SSDT
Updated patch with improved comments and small bugfix (use same
value for min and max on io resource).
While adding the area between TOM1 and 4GB to \SB.PCI0._CRS seems to be the
easiest way to get both Linux and Windows happy, it is not quite correct
because reserved areas like APIC, MMCONF etc. ranges need to be excluded.
This is a proof of concept patch for the M2V board that dynamically creates a
ResourceTemplate() containing these in the SSDT and adds a corresponding
PNP0C02 device to the DSDT.
All resources that have IORESOURCE_RESERVE and (IORESOURCE_MEM or IORESOURCE_IO) set
are added.
