gpu: nvgpu: support kernel-3.10 version

Make necessary changes to support nvgpu on kernel-3.10

This includes below changes
- PROBE_PREFER_ASYNCHRONOUS is defined only for K3.10
- Fence handling and struct sync_fence is different between
  K3.10 and K3.18
- variable status in struct sync_fence is atomic on K3.18
  whereas it is int on K3.10
- if SOC == T132, set soc_name = "tegra13x"
- ioremap_cache() is not defined on K3.10 ARM versions,
  hence use ioremap_cached()
