dtoc: Fix a few pylint warnings in dtb_platdata

These have crept in again. Update the file to fix all but these ones:

   dtb_platdata.py:143:0: R0902: Too many instance attributes (10/7)
      (too-many-instance-attributes)
   dtb_platdata.py:713:0: R0913: Too many arguments (6/5)
      (too-many-arguments)
