[ARM] Kirkwood: add support for newer SoC models
Add support to the Kirkwood port for newer device models and silicon revisions. Instead of looking at the DEVICE_ID register, the device version is now determined by looking at the PCI-Express device ID and revision registers, as it is done for orion5x, and this information is used to determine the TCLK frequency, again, as it is done for orion5x.
