Move the irqlinks.asl file currently in the BayTrail directory to a common place to be shared among all x86 platforms. As the PIRQ routing control programming interface is common to Intel chipsets, leave the common part in the common file, and move the platform specific part to the platform files.

|
* Intel chipset PIRQ routing control ASL description
|
|
*
|
|
* The programming interface is common to most Intel chipsets. But the PRTx
|
|
* registers may be mapped to different blocks. Some chipsets map them to LPC
|
|
* device (00:1f:00) PCI configuration space (like TunnelCreek, Quark), while
|
|
* some newer Atom SoCs (like BayTrail, Braswell) map them to Intel Legacy
|
|
* Block (ILB) memory space.
|
|
*
|
|
* This file defines 8 PCI IRQ link devices which corresponds to 8 PIRQ lines
|
|
* PIRQ A/B/C/D/E/F/G/H. To incorperate this file, the PRTx registers must be
|
|
* defined somewhere else in the platform's ASL files.
