arch/arm: Pass cbmem_top to ramstage via calling argument
This solution is very generic and can in principle be implemented on
all arch/soc.
Instead trying to figure out which files can be removed from stages
and which cbmem_top implementations need with preprocessor, rename all
cbmem_top implementation to cbmem_top_romstage.
Mechanisms set in place to pass on information from rom- to ram-stage
will be placed in a followup commit.
