lib/cbmem_top: Add a common cbmem_top implementation
This adds a common cbmem_top implementation to all coreboot target.
In romstage a static variable will be used to cache the result of
cbmem_top_romstage.
In ramstage if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is set a global variable
needs to be populated by the stage entry with the value passed via the
calling arguments. if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is not set the
same implementation as will be used as in romstage.
