My version (https://github.com/groeck/qemu) seems to work, using 
multi_v7_defconfig.
Logs from boots with qemu 3.0 and 3.1 attached.

Command line:

/opt/buildbot/qemu-install/v3.0/bin/qemu-system-arm \
        -M raspi2 -kernel arch/arm/boot/zImage -no-reboot \
        -snapshot -drive file=core-image-minimal-qemuarm.ext3,format=raw,if=sd \
        --append 'earlycon=pl011,0x3f201000 root=/dev/mmcblk0 rootwait rw 
console=ttyAMA0 noreboot' \
        -dtb arch/arm/boot/dts/bcm2836-rpi-2-b.dtb \
        -nographic -monitor null -serial stdio
