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.

@ Make an educated guess regarding the memory map:
|
|
@ - the original A9 core tile (based on ARM Cortex-A9 r0p1)
|
|
@ should use UART at 0x10009000
|
|
@ - all other (RS1 complaint) tiles use UART mapped
|
|
@ at 0x1c090000
