libata: implement ata_timing_cycle2mode() and use it in libata-acpi and pata_acpi
libata-acpi is using separate timing tables for transfer modes
although libata-core has the complete ata_timing table. Implement
ata_timing_cycle2mode() to look for matching mode given transfer type
and cycle duration and use it in libata-acpi and pata_acpi to replace
private timing tables.
