RELOCATABLE_RAMSTAGE: Fix weak symbols with ramstage_cache 

We had NULL reference with cache_loaded_ramstage() if
CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM was not set so boot never
proceeded to ramstage.

Cache implementation outside CBMEM provides means for platform-specific
location so there is no need of weak attributes here.
