ARM: qemu-arm: Fix qemu_arm64_defconfig for QEMU 3.0

Browse source 
QEMU 3.0 introduced additional memory-mapped regions for PCI-E ECAM and
MMIO. Thus we need to add them to our MMU map or U-Boot will crash with
a Synchronous Abort during PCI-E probing when it tries to access the
unmapped ECAM memory area.
