arm_adi_v5: update coresight class names

Update the list of ARM coresight classes wrt to latest ARM
documentation.
Use c99 array designator to easily track changes in future.
Add a comment for the entry "OptimoDE DESS". It was added in 2009
by David Brownell, but Google cannot find any reference other than
this line in openocd code its associated commit. It should not be
an issue keeping it as is.
