  Use current SP instead of global data ptr for the U-Boot API signature search hint.
  
  Global data (pointed by R2 on PowerPC) in principle is not guaranteed to be in
  proximity of U-Boot heap (where the API signature is placed) accross different
  architectures and platforms. Instead, use U-Boot stack pointer as a hint for
  the search instead of the global data; this method tends to be more uniform
  accross different platforms.
