ata: pata_ns87415: mark ns87560_tf_read static

The global function triggers a warning because of the missing prototype

drivers/ata/pata_ns87415.c:263:6: warning: no previous prototype for 'ns87560_tf_read' [-Wmissing-prototypes]
  263 | void ns87560_tf_read(struct ata_port *ap, struct ata_taskfile *tf)

There are no other references to this, so just make it static.
