All custom ->dma_timeout implementations call the generic one thus it is
possible to have only an optional method for resetting DMA engine instead:
* Add ->dma_clear method and convert hpt366, pdc202xx_old and sl82c105
host drivers to use it.
* Always use ide_dma_timeout() in ide_dma_timeout_retry() and remove
->dma_timeout method.
* Make ide_dma_timeout() static.

* 'thislen' is always <= cmd->nleft for non-fs requests so the transfer

Use the following facts:
- rq->nr_sectors should now be always equal to (non-zero)
rq->hard_nr_sectors for fs requests
- REQ_TYPE_ATA_PC requests have never bio attached to them
- rq->hard_nr_sectors == 0 for REQ_TYPE_ATA_PC requests
- DMA is used only for fs, pc and REQ_TYPE_ATA_PC requests
- 'uptodate' is ignored for pc requests ('rc == 0' case)
and use the common completion path also for DMA requests.

macro thus making ide_debug_log() calls shorter and more readable.

This patch fixes the bug reported in
http://bugzilla.kernel.org/show_bug.cgi?id=11681.
"Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data
outside the device_driver struct as a pointer pointer to the
device driver's suspend_late() function or other hard to
reproduce failures."(Lothar Wassmann)

* Pass pointer to buffer for IDENTIFY data to do_identify()
and try_to_identify().
* Un-static try_to_identify() and use it in ide_driveid_update().
* Rename try_to_identify() to ide_dev_read_id().
There should be no functional changes caused by this patch.

Clear drive IRQ after re-enabling local IRQs in ide_driveid_update()
to match try_to_identify().
Also remove superfluous local_irq_enable() call while at it.
