ide: enhance ide_busy_sleep()

* Make ide_busy_sleep() take timeout value as a parameter
  and also allow use of AltStatus Register if requested with
  altstatus parameter.  Update existing users accordingly.

* Convert ide_driveid_update() and actual_try_to_identify()
  to use ide_busy_sleep().

There should be no functional changes caused by this patch.
