Use the UART0 peripheral for low level debug. Only the UART port 0 is
currently supported.

The PL01X debug code needs to take into account which endian mode the
processor is running in. If it is big-endian, ensure the data is swapped
appropriately.
Note, we could do this slightly more efficiently if we have an macro to
do the necessary swap for the bits used by test.

Now that the PL01X debug include can mostly stand alone without
requiring platforms to provide any macros, move it into the debug
directory so it can be directly included. This allows us to get rid of
a lot of debug-macros include files.
The autodetect case for Versatile Express and the ux500 are left alone;
these are more complicated implementations.
