[U-Boot] [PATCH v3 49/66] rockchip: Makefile: streamline SPL/TPL configuration

Handling TPL and SPL in the Makefile for mach-rockchip was based on
nested if checks and/or if-else-if paths. This can be simplified and
made more readable by using $(SPL_TPL_) and by introducing
intermediate variables for the aggregation of SPL and TPL features.
