Revert "staging: mmal-vchiq: Avoid use of bool in structures"

This reverts commit 640e7746.

In commit 7967656f ("coding-style: Clarify the expectations around
bool") the check to dis-allow bool structure members was removed from
checkpatch.pl. It promotes bool structure members to store boolean
values. This enhances code readability.
