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.
