[U-Boot] [PATCH v2 2/6] x86: ifdtool: Add support for early microcode access

Some Intel CPUs use an 'FSP' binary blob which provides an inflexible means of starting up the CPU. One result is that microcode updates can only be done before RAM is available and therefore parsing of the device tree is impracticle. Worse, the addess of the microcode update must be stored in ROM
