gpu: nvgpu: Make LTC disabling common code

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.
