[PATCH] configs: enable CONFIG_PCI_REGION_MULTI_ENTRY=y in sifive_unmatched_defconfig

[Yuri Zaporozhets]

Currently, the PCI subsystem selects the small "region 2" (which starts at 0x7000000)
as bus_addr/phys_addr. As a consequence, the BAR0 on PCIe video card cannot be initialized,
because it simply doesn't fit into 0x1000000 bytes size of "region 2".

U-Boot should use "region 1" instead (the one which starts at 0x60090000), because
it has much bigger size (0xFF70000), and easily accomodates BAR0 of the video card.
Linux kernel also uses 0x60090000 as bus_start/phys_start.
