[ATA] Increase lba48 max-sectors from 200 to 256.
Also, moved ATA_MAX_SECTORS and ATA_MAX_SECTORS_LBA48 from linux/libata.h to linux/ata.h, now that they truly reflect the standard (well... mostly; note TODO comment). This changes the performance profile (and potential bug profile) for a bunch of drivers, so be wary.
