gpu: nvgpu: Set max_ways_evict_cache to maximum

Browse Source 
This is setting evict_max_ways for L2 cache to the maximum
supported value for safety.

In normal build L2 cache MAX_EVICT_LAST is configure via
KMD and RegOps. RegOps is enabled only on standard build
with CONFIG_DEBUGGER flag. This method we cant use it for
safety build. Safety we can make use of the patch buffer
to patch the register while creating the context.
