libata: reimplement ata_acpi_cbl_80wire() using ata_acpi_gtm_xfermask()
Reimplement ata_acpi_cbl_80wire() using ata_acpi_gtm_xfermask() and
while at it relocate the function below ata_acpi_gtm_xfermask().
New ata_acpi_cbl_80wire() implementation takes @gtm, in both pata_via
and pata_amd, use the initial GTM value. Both are trying to peek
initial BIOS configuration, so using initial caching value makes
sense. This fixes ACPI part of cable detection in pata_amd which
previously always returned 0 because configuring PIO0 during reset
clears DMA configuration.
