ARM: debug-ll: rework footbridge handling
Footbridge has two debug ports that are handled a bit differently: The 8250 port uses the normal debug/8250.S implementation that is shared with a lot of other platforms, but it relies on the DEBUG_UART_8250 option to be turned on automatically instead of being selected by DEBUG_FOOTBRIDGE_COM1 as we do for most other platforms. I'm changing this to use a 'select' and change the dependency to the debug symbol rather than the platform symbol for consistency. The DC21285 UART has a separate top-level option, and relies on the traditional include/mach/debug-macro.S method. With the s3c64xx multiplatform series queued up for 4.5, it is now the last one that does this, so by moving this file to include/debug/dc21285.S, we can get all platforms to do things the same way.
