2dcd4e9ee1 x86: Move efi .S files into the 'lib' directory 
These files now need to be in a standard place so that they can be located
by generic Makefile rules. Move them to the 'lib' directory.

8e36650875 x86: Add helper code for running from EFI 
When U-Boot is running from EFI some of the x86 init is replaced with
EFI-specific init. For example, since DRAM has already been set up, we only
need to find it, not init it. Add these functions so that boards can easily
allow booting from EFI if required.

Add support for building a 32/64-bit EFI stub for x86. This involves
building the startup and relocation code for either i386 or x86_64.
