scc_pata.c: do setup itself instead of ide_setup_pci_device()

scc_pata has the different BAR configuration and using ide_setup_pci_device()
is inappropriate. 

(ide_setup_pci_device() expects a normal PCI IDE controller with
BAR0..BAR3 either non-existant or being primary/secondary port bases
in I/O space.)

This patch do all needed setup itself instead of calling ide_setup_pci_device().
