The spl_phase() function indicates whether U-Boot is in SPL and before or after relocation. But sometimes it is useful to check for SPL with zero code-size impact. Since spl_phase() checks the global_data flags, it does add a few bytes.
Add a new spl_in_proper() function to check if U-Boot proper is running, regardless of the relocation status.
