Vedashree Vidwans e0dd79cd43 gpu: nvgpu: rearch mc reset and enable hals
Remove current mc hals
- mc.reset()
- mc.enable()
- mc.disable()
- mc.reset_mask()
- mc.reset_engine()
- mc.reset_engine_enable()

Add new mc hals
- mc.enable_units(g, units, enable)
  > enable/disable given unit(s)
- mc.enable_dev(g, dev, enable)
  > enable/disable engine represented by given device pointer
- mc.enable_devtype(g, devtype)
  > enable/disable all engines of given devtype

Move common mc intr functions to common/mc/mc_intr.c.
Add below common mc functions
- nvgpu_mc_reset_units(g, units)
  > reset given logical OR of nvgpu unit bitmap
- nvgpu_mc_reset_dev(g, dev)
  > reset given single engine via dev
  > if engine is graphics, reset gpcs for nvgpu_next
- nvgpu_mc_reset_devtype(g, devtype)
  > reset all engines of given devtype
  > if devtype is graphics, reset gpcs for nvgpu_next
