We used to have MSR_DE surrounded by CONFIG_something
to ensure it wasn't set under normal operation.  IIRC, if MSR_DE
is set, you will have problems with software debuggers that
utilize the the debugging registers in the chip itself.  You only want
to force this to be set when using the BDI, not at other times.

Thanks.
