staging: vchiq_arm: Disable ability to dump memory by default
vc04_services has an ioctl interface to dump arbitrary memory
to a custom debug log. This is typically only needed by
diagnostic tools, and can potentially be a security issue
if the devtmpfs node doesn't have adequate permissions set.
Since the ability to dump memory still has debugging value,
create a new build configuration and disable the feature
by default.
