Otherwise, values over 127 end up prefixed with ffffff.

Minimal reproduction:

``` // repro.dts /dts-v1/;

/ { ra = [ 7f ]; rb = [ 80 ]; }; ```

Steps used to compile:

$ dtc repro.dts > repro.dtb

Without the fix:

$ fdtgrep --include-node / repro.dtb / { ra = [7f]; rb = [ffffff80]; };

With the fix:

$ fdtgrep --include-node / repro.dtb / { ra = [7f]; rb = [80]; };
