ide: use ATA_* defines instead of *_STAT and *_ERR ones

* ERR_STAT   -> ATA_ERR
* INDEX_STAT -> ATA_IDX
* ECC_STAT   -> ATA_CORR
* DRQ_STAT   -> ATA_DRQ
* SEEK_STAT  -> ATA_DSC
* WRERR_STAT -> ATA_DF
* READY_STAT -> ATA_DRDY
* BUSY_STAT  -> ATA_BUSY

* MARK_ERR   -> ATA_AMNF
* TRK0_ERR   -> ATA_TRK0NF
* ABRT_ERR   -> ATA_ABORTED
* MCR_ERR    -> ATA_MCR
* ID_ERR     -> ATA_IDNF
* MC_ERR     -> ATA_MC
* ECC_ERR    -> ATA_UNC
* ICRC_ERR   -> ATA_ICRC

* BBD_ERR    -> ATA_BBK

Also:

* ILI_ERR    -> ATAPI_ILI
* EOM_ERR    -> ATAPI_EOM
* LFS_ERR    -> ATAPI_LFS

* CD         -> ATAPI_COD
* IO         -> ATAPI_IO
