Fix several errors and warnings given by checkpatch.pl:
- space between the asterisk and parameter name;
- inconsistent spacing between operator and operands;
- space between *sizeof* and open parenthesis;
- #include instead of #include
- use of *typedef* instead of a structure tag;
- line over 80 characters.
In addition to these changes, also do the following:
- indent with tabs instead of spaces;
- put the function's result type and name/parameters on the same line;
- join back the needlessly broken lines;
- get rid of needless type cast in sgiioc4_checkirq();
- remove space between the type cast and the variable name;
- remove commented out field initializer;
- uppercase the acronyms, lowercase the normal words in the comments;
- fix up the multi-line comment style...

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.

Move apparently misplaced read_sff_dma_status() method from 'struct ide_tp_ops'

Convert the driver to use ide_host_add() -- this seems to be a straightforward

- unnecessary 'goto' and label...
