Currently, hyp_read_ipa_pa_info() only translates IPA for RAM
mappings. It fails for MMIO mappings. In particular, it will
fail when attempting to translate addresses in the syncpoint
shim aperture. As a workaround, assume 1:1 IPA to PA mapping
when hyp_read_ipa_pa_info fails, and address is in syncpt
shim aperture.

Add IPA to PA translation for GV100 nvlink / pass-through mode
- define platform->phys_addr(g, ipa) method
- call nvgpu_init_soc_vars from nvgpu_tegra_pci_probe
- in nvgpu_init_soc_vars, define set platform->phys_addr to
nvgpu_tegra_hv_ipa_pa, if hypervisor is present.
- in __nvgpu_sgl_phys, use sg_phys, then apply platform->phys_addr
if defined.
- implement IPA to PA translation in nvgpu_tegra_hv_ipa_pa

Add nvgpu_* wrappers for determining if we're running in simulation
or silicon, and if we're running in hypervisor.
The new wrappers require struct gk20a pointer, and gk20a_fence_wait()
did not have access to one. Add struct gk20a pointer as the first
parameter.
