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 <asm/io.h> instead of #include <linux/io.h>

- 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...

host drivers to use it.

* Always use ide_dma_timeout() in ide_dma_timeout_retry() and remove
->dma_timeout method.

Move apparently misplaced read_sff_dma_status() method from 'struct ide_tp_ops'
to 'struct ide_dma_ops', renaming it to dma_sff_read_status() and making only
required for SFF-8038i compatible IDE controller drivers (greatly cutting down
the number of initializers) as its only user (outside ide-dma-sff.c and such
drivers) appears to be ide_pci_check_simplex() which is only called for such
controllers...

Use the newly introduced pci_ioremap_bar() function in drivers/ide.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.
