pdc_adma has interface similar to SFF but has its own DMA interface.
It currently implements noop bmdma ops to avoid crashing
ata_bmdma_error_handler() which BTW actually is EH for SFF drivers.
This patch makes ata_bmdma_error_handler() dereference bmdma ops iff
bmdma_addr is initialized as done in ata_bmdma_post_internal_cmd.
This change allows pdc_adma to standardize ops and use SFF
error_handler and post_internal_cmd.

This patch series in on top of #cleanup-sht-ops (ed75ba53) and not for
#upstream-fixes. Tested with pdc_adma controllers Mark sent me. :-)

I realize now that the lack of this patchset (broken ordering on my
part) probably caused the previously-emailed-about compile breakage.
sorry! I'll pull the rest after a resync, since I ack'd that 27-patch
patchset.
