pata_hpt37x: Fix 2.6.22 clock PLL regression
Just one version of Linux ago The PLL code broke - oh no! But set the right mode And fix up the code Makes the PLL timing sync go [whatever happened to the sailor from Nantucket, hero of many limericks? -jg] Closes-bug: #8791 Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
