thunderbolt: Add initial cactus ridge NHI support Thunderbolt hotplug is supposed to be handled by the firmware. But Apple decided to implement thunderbolt at the operating system level. The firmare only initializes thunderbolt devices that are present at boot time. This driver enables hotplug of thunderbolt of non-chained thunderbolt devices on Apple systems with a cactus ridge controller. This first patch adds the Kconfig file as well the parts of the driver which talk directly to the hardware (that is pci device setup, interrupt handling and RX/TX ring management).

thunderbolt: Add support for Intel Ice Lake The Thunderbolt controller is integrated into the Ice Lake CPU itself and requires special flows to power it on and off using force power bit in NHI VSEC registers. Runtime PM (RTD3) and Sx flows also differ from the discrete solutions. Now the firmware notifies the driver whether RTD3 entry or exit are possible. The driver is responsible of sending Go2Sx command through link controller mailbox when system enters Sx states (suspend-to-mem/disk). Rest of the ICM firwmare flows follow Titan Ridge.

thunderbolt: Move LC specific functionality into a separate file We will be adding more link controller functionality in subsequent patches and it does not make sense to keep all that in switch.c, so separate LC functionality into its own file.
