Is this MultiGBASE-T test mode register (Register 1.132)?

The test mode control is not a single bit, but three bits. So you
should not be using BIT(13).

Since this is a standard part of C45, please add a helper to phy-c45.c

Another thing i want to take a look at is the locking. It is pretty
ugly having to use so many __ functions, and not being able to use the
helpers. I want to see if we can avoid this.
