Subject: [PATCH v2 1/3] Revert "staging: mmal-vchiq: Avoid use of bool in structures"

This reverts commit 640e77466e69d9c28de227bc76881f5501f532ca.

In commit 7967656ffbfa ("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.
