libata: separate out ata_acpi_gtm_xfermask() from pacpi_discover_modes()
Finding out matching transfer mode from ACPI GTM values is useful for
other purposes too. Separate out the function and timing tables from
pata_acpi::pacpi_discover_modes().
Other than checking shared-configuration bit after doing
ata_acpi_gtm() in pacpi_discover_modes() which should be safe, this
patch doesn't introduce any behavior change.
