x86: qemu: fix cpu device in smp boot
Currently, when booting with more that one CPU enabled, U-Boot scans 'cpu' node in device tree and calculates CPU number. This does not scale well as changing CPU number also requires modifying .dts and re-compiling U-Boot. This patch uses fw_cfg interface provided by QEMU to detect online CPU number at runtime, and dynamically adds 'cpu' device to U-Boot's driver model.
