The zero day bot reported some sparse complaints in pata_falcon.c. E.g.

drivers/ata/pata_falcon.c:58:41: warning: cast removes address space '__iomem' of expression
drivers/ata/pata_falcon.c:58:41: warning: incorrect type in argument 1 (different address spaces)
drivers/ata/pata_falcon.c:58:41:    expected unsigned short volatile [noderef] [usertype] __iomem *port
drivers/ata/pata_falcon.c:58:41:    got unsigned short [usertype] *

The same thing shows up in 8 places, all told. Avoid this by removing
unnecessary type casts.
