linux-next: manual merge of the tty tree with the powerpc tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi Greg,

Today's linux-next merge of the tty tree got a conflict in
drivers/tty/serial/8250.c between commit 7df5659eefad ("serial/8250: Move
UPIO_TSI to powerpc") from the powerpc tree and commit 4834d0289785
("tty: serial8250: remove UPIO_DWAPB{,32}") from the tty tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.
