confusion re: CPM2 and 8xxx

[Kumar Gala]

I think this is due to the config file just not getting updated.  The
driver for the uart on CPM1 (8xx) and CPM2 (82xx/85xx) is the same
code.  It started as a driver for only CPM2 and thus the config options
reference CPM2.  Will make a note to cleanup the config file for the
driver
