thunderbolt: Fix header declaration of tb_find_cap
tb_find_cap in cap.c takes an enum tb_cap and not an u32. Fix the
declaration in tb.h.

thunderbolt: Read port configuration from eeprom.
All Thunderbolt switches (except the root switch) contain a drom which
contains information about the device. Right now we only read the UID.
Add code to read and parse this drom. For now we are only interested in
which ports are disabled and which ports are "dual link ports" (a
physical thunderbolt port/socket contains two such ports).

thunderbolt: Add suspend/hibernate support
We use _noirq since we have to restore the pci tunnels before the pci
core wakes the tunneled devices.

thunderbolt: Read switch uid from EEPROM
Add eeprom access code and read the uid during switch initialization.
The UID will be used to check device identity after suspend.

thunderbolt: Add support for simple pci tunnels
A pci downstream and pci upstream port can be connected through a
tunnel. To establish the tunnel we have to setup two unidirectional
paths between the two ports.
Right now we only support paths with two hops (i.e. no chaining) and at
most one pci device per thunderbolt device.

thunderbolt: Add path setup code.
A thunderbolt path is a unidirectional channel between two thunderbolt
ports. Two such paths are needed to establish a pci tunnel.
This patch introduces struct tb_path as well as a set of tb_path_*
methods which are used to activate & deactivate paths.

thunderbolt: Handle hotplug events
We receive a plug event callback whenever a thunderbolt device is added
or removed. This patch fills in the tb_handle_hotplug method and starts
reacting to these events by adding/removing switches from the hierarchy.
