[PATCH u-boot-marvell 02/16] ddr: marvell: a38x: debug: return from ddr3_tip_print_log() early if we won't print anything

Return from ddr3_tip_print_log() early if we won't print anything
anyway.
This way the compiler can optimize away the VALIDATE_IF_ACTIVE() calls
in the for-loop, so if the SILENT_LIB macro is defined, no code is
generated for the rest of the function, which saves some space.
