In preparing to remove the .adjust_link api, I am moving the one-time initialization of the device's Turbo Mode bit into a different execution path. This code clears (disables) the Turbo Mode bit which is never used by this driver. Turbo Mode is a non-standard mode that would allow the 100Mbps RMII interface to run at 200Mbps.
