ide: add ide_tf_read() helper
* Factor out code reading taskfile registers from ide_end_drive_cmd()
to the new ide_tf_read() helper.
* Add IDE_TFLAG_IN_* taskfile flags to indicate the need to load
particular IDE taskfile register in ide_tf_read().
* Update ide_end_drive_cmd() to set respective IDE_TFLAG_IN_* taksfile flags.
* Add ide_get_lba_addr() for getting LBA sector address from taskfile struct.
* Factor out code getting sector address from ide_dump_ata_status()
to the new ide_dump_sector() function.
* Convert ide_dump_sector() to use ide_tf_read() and ide_get_lba_addr().
* Remove no longer needed ide_read_24().
The only change in functionality caused by this patch is that
ide_dump_ata_status() no longer prints "high"/"low" parts of LBA48
sector address (of course LBA48 sector address is still printed).
