Tejun Heo c729072459 ata_piix: implement SIDPR SCR access 
For ICH8, SCRs can be accessed using index and data register pair
located at BAR 5.  This patch implements support for it such that PHY
status, errors and hardreset are available for those controllers.

This is the only case where two devices on a PATA channel have access
to SCRs and creates a unique problem of mapping two SCRs to one link.
Note that this is different from PMP case in that they aren't quite
separate links - e.g. softreset resets both devices.

This problem is worked around by merging the SCR values.  To upper
layer, it looks like there is a single link with one set of SCRs but
with two devices.  This works well enough for PHY event, error
reporting and hardreset.

Supporting hardreset is important because in rare cases SATA devices
fail to recover without it after PHY errors.
