The PSL initialization sequence has been updated to DD2.
This patch adapts to the changes, retaining compatibility with DD1.
Tests performed on some of the new hardware.

If we're retaining compatibility with DD1 I assume it's been tested on
some of the old hardware too?
It seems this includes some changes to DD1 fix-ups as well.

I was confused by this comment for a while - maybe keep PSL_TNR_ADDR at
the beginning of the comment, it's not completely clear from the
previous block alone.

Please wrap this block that configures the trace arrays in #ifdef
DEBUG. Or it will be better if we remove it from here as the register is
already accessible via debugfs.
