update checkpatch.pl to version 0.09

This version brings a number of new checks, and a number of bug
fixes.  Of note:

  - checks for spacing on round and square bracket combinations
  - loosening of the single statement brace checks, to allow
    them when they contain comments or where other blocks in a
    compound statement have them.
  - parks the multple declaration support
  - allows architecture defines in architecture specific headers
