Refactor the sync_debugfs LTC HAL op so that the logic to enable or disable LTC goes to common code nvgpu_ltc_sync_enabled() and the LTC HAL set_enabled only performs the hardware register access. Create a new common function nvgpu_init_ltc_support() to initialize the LTC software variable, and move hardware initialization of LTC to be called from it.
