Subject: [PATCH v4 0/5] g_NCR5380: PDMA fixes and cleanup

Ondrej, would you please test this new series?

Changed since v1:
- PDMA transfer residual is calculated earlier.
- End of DMA flag check is now polled (if there is any residual).

Changed since v2:
- Bail out of transfer loops when Gated IRQ gets asserted.
- Make udelay conditional on board type.
- Drop sg_tablesize patch due to performance regression.

Changed since v3:
- Add Ondrej's workaround for corrupt WRITE commands on DTC boards.
- Reset the 53c400 logic after any short PDMA transfer.
- Don't fail the transfer if the 53c400 logic got a reset.
