[PATCH] SATA: fix and enable sata-sil

sata_sil:  it's a widely deployed chipset.  Now that we've fixed it, let
users use it.

sata_via:  Disk detection via SATA phy registers appear problematic. 
Until that problem is identified and fixed, used the old PATA detection 
code -- that was used in 2.6.4 -- instead.
