gpu: nvgpu: Remove dependency on DGPU CONFIG

Browse Source 
The error injection code was enabled only when CONFIG_NVGPU_DGPU = n
so that the dGPUs do not attempt any error injection callback
function registration. But, this introduced dependency on DGPU
config when needs to be explicitly set to n for error injection to
be enabled.
Remove the dependency by moving the error injection callback
registration and deregistration to a HAL which is enabled only
on GA10b.
