Subject: [PATCH 6/6] seabios: increase the seabios high mem zone size

In terms of version and specification, under the maximum configuration
specification of the number of vcpus, virtio blocks and other features,
there exists bottleneck in seabios high_mem_zone, which results in the
memory application failure and causes the vm to fail to start.

Increase BUILD_MAX_HIGHTABLE to 512k.
