It sounds like pata_via and pata_amd need a foo_save_initial_config()
much like AHCI, during which they would fill ppriv->init_gtm rather than
ap->init_gtm. Thoughts? Both drivers are calling ata_acpi_cbl()
themselves, permitting the possibility of ppriv->init_gtm.
This avoids forcing everyone else to bear the memory cost in ata_port
for just these two drivers.
