[PATCH] cpm_uart: Make non-console uart work (rev 1)

Kumar, Pantelis,

This patch makes non-console UART work on both 8xx and 82xx. dpram 
allocation fix by Pantelis included, almost all mentioned issues fixed.

Tested on 8272ADS development board, but as far as there are no major 
modifications comparing to previous revision (excluding Pantelis change 
which has been tested independently), 8xx should work as well.
