kmp204x: implement workaround for A-006559
According to the errata, some bits of an undocumented register in the
DCSR must be set for every core in order to avoid a possible data or
instruction corruption.
This is required for the 2.0 revision of the P2041 that should be used
as soon as available in our design.
