gpu: nvgpu: Fix build failure in allocator.h

Browse Source 
Fix a build failure caused by missing definition for struct device.
Instead of including device.h wrap the debugfs init function with
CONFIG_DEBUG_FS and forward declare struct device. We don't use any
struct device internals here so we only need to let the compiler
know that this type does exist.
