[PATCH 14/15] ata: libata-acpi: Fix function name and provide description for 'prev_gtf'

[Lee Jones]

Fixes the following W=1 kernel build warning(s):

 drivers/ata/libata-acpi.c:493: warning: expecting prototype for ata_acpi_gtm_xfermode(). Prototype was for ata_acpi_gtm_xfermask() instead
 drivers/ata/libata-acpi.c:648: warning: Function parameter or member 'prev_gtf' not described in 'ata_acpi_run_tf'
