ide: remove task_ioreg_t typedef (take 2) 

Remove task_ioreg_t typedef from the kernel code (but leave it
in <linux/hdreg.h> for #ifndef/#endif __KERNEL__ case).

While at it also move sata_ioreg_t typedef under #ifndef/#endif __KERNEL__.

v2:
Remove name of the second parameter from ide_execute_command() declaration.
(Noticed by Sergei).
