------------------------------------------------------
Subject: libata: export xfermode / PATA timing related functions
From: Tejun Heo <htejun@xxxxxxxxx>
Export the following xfermode related functions.
* ata_pack_xfermask()
* ata_unpack_xfermask()
* ata_xfer_mask2mode()
* ata_xfer_mode2mask()
* ata_xfer_mode2shift()
* ata_mode_string()
* ata_id_xfermask()
* ata_timing_find_mode()
These functions will be used later by LLD updates. While at it,
change unsigned short @speed to u8 @xfer_mode in
ata_timing_find_mode() for consistency.
