meta-phosphor: nuvoton-layer: generate full flash image.

Nuvoton's full flash image includes also a bootloader called Bootblock,
and headers for it and for the u-boot. Generating headers and merging
the Bootblock and the u-boot are being done by Nuvoton's binary
generator tool (Bingo), which uses external paramteres from XML files
for that.
