drivers/intel/fsp2_0: separate component validation from loading
The current FSP component loading mechanism doesn't handle all the
requirements actually needed. Two things need to be added:
1. XIP support for MemoryInit component
2. Relocating SiliconInit component to not corrupt OS memory.
In order to accommodate those requirements the validation
and header initialization needs to be a separate function.
Therefore, provide fsp_validate_component() to help achieve those
requirements.
