Subject: [PATCH] POWERPC CPM: Minor cosmetic changes to udbg_putc

From: Nye Liu <nyet@....com>

udbg_putc is a *function pointer* that is initialized during
udbg_init_cpm. It might not be initialized properly when called from
udbg_putc_cpm(), so (recursively) call udbg_putc_cpm() directly.

Printing an "X" on initialization is ugly. How about a "\n" instead?
