mb/lenovo/t400: Improve docking code
* Remove dead code
* Add support for types 2504 and 2505
* Print dock info at romstage entry
* Improve dock disconnect for type 2505
* Move defines into dock.h for future ACPI code
* Reduce timeouts according to spec to decrease boot time on error
* Fix no docking detection (reduces boot time by 1 second)
* Configure GPIO LDN before reading GPIOs
* Use Kconfig values instead of fixed defines
* Add documentation
Tested on Lenovo T500 with docking 2504 and 2505.
