lib: Update fmap cache error for psp_verstage 

The assumption was that the fmap cache would be initialized in
bootblock, otherwise an error is shown.  This error is showing
up in psp_verstage when the fmap cache is initialized there, so
create a new ENV value for ENV_INITIAL_STAGE.

BUG=None
TEST=Boot, see that error message is gone from psp_verstage
