72291a9d83 efi_loader: fix freestanding memmove() 
For EFI binaries we have to provide an implementation of memmove() in
efi_freestanding.c.

Before this patch the memmove() function was copying in the wrong
direction.

9bb758aab6 efi_loader: __cyg_profile_func_enter/_exit 
U-Boot can be compiled with function tracing enabled.

When compiling with FTRACE __cyg_profile_func_enter() is called when a
function is entered and __cyg_profile_func_exit() when the function is
left.

To avoid a crash we have to define these function for the free-standing
UEFI binaries.

GCC requires that freestanding programs provide memcpy(), memmove(),
memset(), and memcmp().

Provide the required library functions.
