[U-Boot] Compile error with CONFIG_MULTI_DTB_FIT and not SPL

[Lars Povlsen]

When changing some MIPS configs from CONFIG_OF_EMBED to
CONFIG_OF_SEPARATE, I ran into this compile issue since SPL is not
enabled. The fix is to guard the <spl.h> header with the
CONFIG_SPL_LIBCOMMON_SUPPORT preprocessor symbol.

It seems that the <spl.h> is not needed even when SPL is enabled, but
I'm not 100% sure on that. The code at lines 55..57 guarded by
CONFIG_SPL_LIBCOMMON_SUPPORT does not require the <spl.h> header file.
