PCI: keystone: Don't enable BAR 0 for AM654x

After 6ab15b5e7057 ("PCI: dwc: keystone: Convert .scan_bus() callback to
use add_bus"), ks_pcie_v3_65_add_bus() enabled BAR 0 for both v3.65a and
v4.90a devices.  On the AM654x SoC, which uses v4.90a, enabling BAR 0
causes Completion Timeouts when setting up MSI-X.  These timeouts delay
boot of the AM654x by about 45 seconds.

Move the BAR 0 initialization to ks_pcie_msi_host_init(), which is only
used for v3.65a devices, and remove ks_pcie_v3_65_add_bus().
