openocd: fix Yoda conditions with checkpatch

The new checkpatch can automatically fix the code, but this
feature is still error prone and not complete.

Patch generated automatically through the new checkpatch with
flags "--types CONSTANT_COMPARISON --fix-inplace".

Some Yoda condition is detected by checkpatch but not fixed; it
will be fixed manually in a following commit.
