ide: add struct ide_io_ports (take 3)
* Add struct ide_io_ports and use it instead of `unsigned long io_ports[]` in ide_hwif_t. * Rename io_ports[] in hw_regs_t to io_ports_array[]. * Use un-named union for 'unsigned long io_ports_array[]' and 'struct ide_io_ports io_ports' in hw_regs_t. * Remove IDE_*_OFFSET defines. v2: * scc_pata.c build fix from Stephen Rothwell. v3: * Fix ctl_adrr typo in Sparc-specific part of ns87415.c. (Noticed by Andrew Morton) Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
