gpu: nvgpu: assume 1:1 IPA to PA mapping for syncpt
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.
