Hi

The following patch updates the new CPM1/CPM2 uart driver.

Its main features are:

1. The driver is moved on it's own directory within drivers/serial.

2. The defines used on the previous driver are removed and
   the different operations for CPM1/CPM2 are moved to their own
   files.

3. The new DMA api is utilized.

Regards

Pantelis

P.S. Apologies for the bziped patch, but the list limit is too small.
