ramstage: Add cbmem_get_table_location()
When CONFIG_EARLY_CBMEM_INIT is selected romstage is supposed to have
initialized cbmem. Therefore provide a weak function for the chipset
to implement named cbmem_get_table_location(). When
CONFIG_EARLY_CBMEM_INIT is selected cbmem_get_table_location() will be
called to get the cbmem location and size. After that cbmem_initialize()
is called.
