Ben Dooks 6ef4e47926 ARM: debug: fix big endian operation for 8250 word mode 
If the 8250 debug code is used in word mode on an big endian
host then the writes need to be change into little endian for
the bus.

Note, we have to re-convert the value back as the debug code
will inspect the value after writing it to see if a newline
has been written.

Russell King 0b4cccbec6 ARM: debug: add support for word accesses to debug/8250.S 
Add 32-bit word access support to debug/8250.S and convert Picoxcell
and SoCFPGA to this.

Russell King 2facbc8873 ARM: debug: move 8250 debug include into arch/arm/include/debug/ 
Now that the 8250 debug include can 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.
