ide: remove hwgroup->hwif and {drive,hwif}->next
* Add 'int port_count' field to ide_hwgroup_t to keep the track
of the number of ports in the hwgroup. Then update init_irq()
and ide_remove_port_from_hwgroup() to use it.
* Remove no longer needed hwgroup->hwif, {drive,hwif}->next,
ide_add_drive_to_hwgroup() and ide_remove_drive_from_hwgroup()
(hwgroup->drive now only denotes the currently active device
in the hwgroup).
* Update locking documentation in <linux/ide.h>.
While at it:
* Rename ->drive field in ide_hwgroup_t to ->cur_dev.
* Use __func__ in ide_timer_expiry().
