This patch renames ioport_shift member of pata_platform_info
structure to reg_shift. Users of pata_platform are followed
appropriately.

Rationale of that change is: shifting applies to the whole memory
mapped region, not only to the command block of the ATA registers,
despite the fact that shifting is meaningless for ctl register.

It's called ioport_shift because of the fact it shifts an ioport, namely
a struct ata_ioport *. We could rename it, but I really don't see the
point. If you don't like the choice of name on your platform, add a
comment to your platform-specific code noting this particular outrage so
it can be grepped for by future generations ;-)
