Provide common functions for accessing CBMEM and coreboot table entries instead of mapping them manually in each function. New functions return a copy of requested region as a heap-allocated buffer thus avoiding a need for aligned memory access. Remove global variables wherever possible to make code easier to read and to isolate responsibilities of functions. Use CBMEM entries instead of coreboot table records directly, but provide fallback for old systems in case the correcponding CBMEM entry does not exist.
