sata_sil24: replace sil24_update_tf() with sil24_read_tf()
Replace sil24_update_tf() to sil24_read_tf() which reads TF into passed int result TF argument and can read TFs of PMP links. This will be used by PMP support. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
