Preserve datatype information when parsing dts

Browse source 
The current code throws away all the data type and grouping information
when parsing the DTS source file, which makes it difficult to
reconstruct the data format when emitting a format that can express data
types (ie. dts and yaml). Use the marker structure to mark the beginning
of each integer array block (<> and []), and the datatype contained in
each (8, 16, 32 & 64 bit widths).
