CBMEM: Add cbmem_locate_table()
For both romstage and ramstage, this calls an arch-specific function get_cbmem_table() to resolve the base and size of CBMEM region. In ramstage, the result is cached as the query may be relatively slow involving multiple PCI configuration reads. For x86 CBMEM tables are located right below top of low ram and have fixed size of HIGH_MEMORY_SIZE in EARLY_CBMEM_INIT implementation.
