[POWERPC] Remove useless volatiles in udbg_16550.c
This removes "volatile" from the MMIO pointer udbg_comport in udbg_16550.c driver, it's useless and makes checkpatch.pl complain when adding things to this file. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
