PCI subsystem: Drop PCI_64BIT_PREF_MEM option

No board in the tree selects this and it looks like the implementation
was done at chipset level while it should be part of PCI subsystem.

When enabled, at least AMD K8 and f14, f15tn and f16kb fail build test.

Feature of placing prefetchable PCI memory above 4GB may not work if
there is any 32-bit only prefetchable PCI BARs in the system.
