gpu: nvgpu: whitelist MISRA 8.7 violations

Browse Source 
Whitelist false positives caused by a Coverity scanner bug
where Advisory Rule 8.7 violations are raised when both
'static' and 'const' are used in the definition of an object.

This bug exists in Coverity v2019.06 and is reported to be
fixed in Coverity v2019.12.

See nvbug 2823817 for more information.
