util/rockchip: Port make_idb.py to python3

BUG=chromium:1023662
TEST=buildbot pass
TEST=1. Use python2 script
     2. Run `emerge-kevin coreboot` twice, so we get bootblock.bin.1
     and bootblock.bin.2
     3. Run `xxd` on these two bootblock so we get bootblock.bin.1.hex
     and bootblock.bin.2.hex
     4. `diff bootblock.bin.1.hex bootblock.bin.2.hex` and record the
     difference. (at least, the time info changes)
     5. Migrate to python3
     6. Similar steps, we get bootblock.bin.py3.hex
     7. `diff bootblock.bin.1.hex bootblock.bin.py3.hex`, the difference
     is similar. (time info, git hash changes)
