xhci: Add Lynx Point to list of Intel switchable hosts.
The upcoming Intel Lynx Point chipset includes an xHCI host controller that can have ports switched from the EHCI host controller, just like the Intel Panther Point xHCI host. This time, ports from both EHCI hosts can be switched to the xHCI host controller. The PCI config registers to do the port switching are in the exact same place in the xHCI PCI configuration registers, with the same semantics. Hooray for shipping patches for next-gen hardware before the current gen hardware is even available for purchase! This patch should be backported to stable kernels as old as 3.0, that contain commit 69e848c2 "Intel xhci: Support EHCI/xHCI port switching."
