libata: clean up xfermode / PATA timing related stuff
* s/ATA_BITS_(PIO|MWDMA|UDMA)/ATA_NR_\1_MODES/g * Consistently use 0xff to indicate invalid transfer mode (0x00 is valid for PIO_SLOW). * Make ata_xfer_mode2mask() return proper mode mask instead of just the highest bit. * Sort ata_timing table in increasing xfermode order and update ata_timing_find_mode() accordingly. This patch doesn't introduce any behavior change. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
