The PIPE_INTERRUPT flag is used wrong

At a lot of places in the code the PIPE_INTERRUPT flags and friends
are used wrong. The wrong bits are compared to this flag resulting
in wrong conditions. Also there are macros that should be used for
PIPE_* flags.
This patch tries to fix them all, however, I was not able to test the
changes, because I do not have any of these boards.

Review required!
