video: tegra: host: CPU reg read to use power management
CPU register read did not have access to nvhost power management.
Due to this only modules that were powered on previously are actually
accessible via the API. This patch refactors CPU access to:
* Move mutexes to sync point, as they're sync point operations
* Move register address spaces to nvhost_device
* Call register read with access to the respective nvhost_device
* Initialize module completely at boot-up so that register reads
can be done without an initialized channel.
