MIPS: drop redundant debug_ll_outhexw macro defines

The debug_ll_outhexw macro has no dependency on UART model
so we can remove it from UART-dependent header files (debug_ll_ns16550.h
and mach-ath79/.../debug_ll.h).

On the other hand the only debug_ll_outhexw user is MIPS nmon monitor
so we can move the debug_ll_outhexw macro to pbl_nmon.h.
