Add debug UART functions to permit ns16550 to provide an early debug UART. Try to avoid using the stack so that this can be called from assembler before a stack is set up (at least on ARM and PowerPC).

Changes in v2:
- Split series out on its own
- Add x86 support (asmlinkage, so it still needs a stack at present)
- Add better cover letter
Applied to u-boot-dm.
