drm/tilcdc: Atomic modeset support

This series implements atomic modeset for TI's LCDC HW. The code has been tested on X-server, weston, and our kmsxx kms testing suite. The patches are based on my earlier tilcdc fixes and cleanups series [1].

I know that the tiny display pipe has been accepted for mainline and I have intention of moving lcdc on top of it at some point. However, there is just too many things I would still have to reimplemet to do it now. How to deal with different encoders, connectors and panels for example. This series should be considered as a first step towards making that move. It implements many things that are needed in simple display pipe too.

There is a lot of changes since RFC version of the series and this is not a complete list:

- Added patches
- drm/tilcdc: Fix tilcdc component master unloading
- drm/tilcdc: Make tilcdc_crtc_page_flip() work if crtc is not yet on
- drm/tilcdc: panel: Set crtc panel info at init phase
- drm/tilcdc: panel: Add atomic modeset helpers to connector funcs
- drm/tilcdc: tfp410: Set crtc panel info at init phase
- drm/tilcdc: tfp410: Add atomic modeset helpers to connector funcs
- drm/tilcdc: Enable and disable interrupts in crtc start() and stop()
- drm/tilcdc: Use drm_atomic_helper_resume/suspend()
- drm/tilcdc: Get rid of legacy dpms mechanism
- drm/tilcdc: Remove unnecessary pm_runtime_get() and *_put() calls
- drm/tilcdc: Change tilcdc_crtc_page_flip() to tilcdc_crtc_update_fb()
- At least following changes to the "old" patches
- Add mechanism to update crtc state's mode_changed if plane fb pixel_format changes
- Add tilcdc_atomic_check() for mode_config_funcs
- Leave tilcdc_crtc_mode_fixup() connected to drm_crtc_helper_funcs
