Implement load_image in terms of IO abstraction
The modified implementation uses the IO abstraction rather than
making direct semi-hosting calls. The semi-hosting driver is now
registered for the FVP platform during initialisation of each boot
stage where it is used. Additionally, the FVP platform includes a
straightforward implementation of 'plat_get_image_source' which
provides a generic means for the 'load_image' function to determine
how to access the image data.
