crossystem: Add the ddr_type field on crossystem for querying DDR RAM type
Samsung want to know what memory type on the device. So this CL adds a
new field ddr_type to crossystem utility in order to query this info.
It is only available on ARM platform so far.
BUG=chrome-os-partner:10857
TEST=Built and boot on Snow successfuly. On userspace, query the field via:
localhost ~ # crossystem ddr_type
ddr3
