ide: add struct ide_taskfile (take 2)
* Don't set write-only ide_task_t.hobRegister[6] and ide_task_t.hobRegister[7]
in idedisk_set_max_address_ext().
* Add struct ide_taskfile and use it in ide_task_t instead of tfRegister[]
and hobRegister[].
* Remove no longer needed IDE_CONTROL_OFFSET_HOB define.
* Add #ifndef/#endif __KERNEL__ around definitions of {task,hob}_struct_t.
While at it:
* Use ATA_LBA define for LBA bit (0x40) as suggested by Tejun Heo.
v2:
* Add missing newlines. (Noticed by Sergei)
* Use ~ATA_LBA instead of 0xBF. (Noticed by Sergei)
* Use unnamed unions for error/feature and status/command.
(Suggested by Sergei).
There should be no functionality changes caused by this patch.
