PCM only mode need a special protocol and a mechanism to set/get/store
the PCM slots of the card, and this is for what the extra stuff is used.

It changed the values of some macros which are actually used by the
code.

Then it adds members to structures, and defines, which are completely
unused.

The latter part is completely bogus.

This is the second time I'm saying this again.  I'm not saying it
a third time, instead I'll just ignore you.
