host: vi: Deprecate nvhost_module_pm_ops

Browse Source 
Deprecate the usage of nvhost_module_pm_ops as part of the wider
nvhost API deprecation while maintaining equivalent functionality.

The VI driver does not register prepare_poweroff, poweron_reset,
finalize_poweron callbacks nor set the clock gating regs with nvhost,
so the runtime operations will only call clk APIs.
