[PATCH v1 38/54] x86: fsp: Update the FSP API with the end-firmware method

[Simon Glass]

This new method is intended to be called when UEFI shuts down the 'boot
services', i.e. any lingering code in the boot loader that might be used
by the OS.

Add a definition for this new method and update the comments a little.
