armv7: Add emulation/qemu-armv7 board.

To simplify testing ARM implementation, we need a QEMU configuration for
ARM. The qemu-armv7 provides serial output, CBFS simulation, and full
boot path (bootblock, romstage, ramstage) to verify the boot loader

To run with QEMU:
 export QEMU_AUDIO_DRV=none
 qemu-system-arm -M vexpress-a9 -m 1024M -nographic -kernel build/coreboot.rom

Verified to boot until ramstage loaded successfully by QEMU v1.0.50.
