Mikko Perttunen 7009b78bb9 gpu: host1x: Don't skip assigning syncpoints to channels 
[ Upstream commit eb258cc1fd ]

The code to write the syncpoint channel assignment register
incorrectly skips the write if hypervisor registers are not available.

The register, however, is within the guest aperture so remove the
check and assign syncpoints properly even on virtualized systems.

Fixes: c3f52220f2 ("gpu: host1x: Enable Tegra186 syncpoint protection")
