[PATCH] ppc64: Clean up CR handling
Make the 16550 and real mode 16550 use tail recursion like the scc code instead of repeating the routine except for the character sent. Gcc recoginizes the tail recursion and handles it efficently without stack allocations. The maple real putc shrinks from 188 to 104 bytes of instructions. udbg_putc drops from 188 to 140 bytes.
