Add type field to memranges, and fill it from the source data. 

type field contains e820 type ids, which are used by coreboot
and multiboot (the two source formats), so they can be used
as-is.

The MEMMAP_RAM_ONLY define is a way to allow a payload to opt
for only having CB_MEM_RAM type fields, which might be helpful
to support older payloads easily (just add the define, and it
won't encounter "weird" fields)
