[PATCH 2.6.13] Fix pio_mask values

[Brett Russ <russb@emc.com>]

ata_get_mode_mask() has PIO modes 3 and 4 as bits 3 and 4 in the pio_mask
since the value read from the drive is shifted left by 3 bits and OR'd with
0x7 (which corresponds to PIO 2-0).  Thus, the drivers below need adjustments
to comply with the way pio_mask is used.  I left the masks in a state which
agrees with the existing comments; perhaps they all should get 0x1f to
indicate driver support for PIO4-0 but that can be done later.
