spl: Add methods to find the position/size of next phase
Binman supports writing the position and size of U-Boot proper and SPL
into the previous phase of U-Boot. This allows the next phase to be easily
located and loaded.
Add functions to return these useful values, along with symbols to allow
TPL to load SPL.
