Vedashree Vidwans 673cd507a8 gpu: nvgpu: add mm gops to get default va size ...

Currently, default va aperture size, user size and kernel size are
defined as fixed macros. However, max va bits can be chip specific.
Add below mm gops API to obtain default aperture, user and/or kernel
virtual memory size.
void (*get_default_va_sizes)(u64 *aperture_size,
		u64 *user_size, u64 *kernel_size);
