lib/device_tree.c: Fix print_property

This uses the size attribute to traverse the possible string.
This patch traverses the entire property for non printable characters
and not just until the first 0 is hit.

Now numbers that start with a zero (memory wise) are not falsely
recognized as strings:

before the patch:
clock-frequency = "";

after the patch:
clock-frequency = < 0x1c2000 >;
