gpu: nvgpu: remove cyclic dependency between gr and ecc

Browse Source 
Removed gr dependency on ecc by moving ecc init/remove support
calls to nvgpu_init. With this, only dependency from ecc to gr
present.

Added following parameter in struct nvgpu_ecc to check/update ecc
initialization status:
bool initialized;
