scripts/dts: fix support for uint8-array property values
uint8-array is the name for what the devicetree specification calls a
bytestring.
The original parsing code treated square brackets as equivalent to
quotes or angle brackets, failing to interpret elements as hex-encoded.
This was a bug, corrected in this patch by processing content as a
sequence of hex-encoded bytes with arbitrary whitespace.
The original generating code emitted the property as individual
elements. Replace that with generation of a single structure
initializer, which is more useful in cases where the length of a
property value may vary between nodes.
