Assign true or false to boolean variables instead of an integer value.

This issue was detected with the help of Coccinelle.

Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com>

Changes in v2:
 - Use true for boolean value in add_detailed_mode as suggested by Daniel
   Vetter.
 - Update subject.

I suppose you could also fix up the other preferred assignment by adding !!
to the bitwise & operation.

It's also helpful to post the spatch in the commit message so others can
replicate your result (this case is pretty trivial, so less important).

Assigning >1 to a bool is well defined. No need to clutter the code with
!! imo.
