Konsta Holtta d49d64e720 gpu: nvgpu: store usermode regs bus addr directly ...

Instead of just the base address of the main register range, store
(also) the base address of usermode area. All regs may not be always
available; on vgpu guests we have only the usermode regs.

Store the usermode addr we get from a platform resource directly in
gv11b_vgpu_probe() for vgpu. In that case the main reg addr is unset.

The base address is computed in gk20a_pm_finalize_poweron() for native
environments; when the reg addr is read from a resource, the chip is
still unknown and as such the HAL op for reading the usermode base
offset is unavailable.
