Subject: [PATCH V6 0/4] Add support for TI VIP

This patch series adds support for the TI VIP. VIP stands for Video
Input Port, it can be found on devices such as DRA7xx and provides
a parallel interface to a video source such as a sensor or TV decoder.

Each VIP can support two inputs (slices) and a SoC can be configured
with a variable number of VIP's. Each slice can support two ports
each connected to its own sub-device.

Changelog:
Changes in v6:
- Collect R/B from Rob
- Use latest v4l-utils (Hans) 
- Remove 'default n' from VIDEO_TI_VIP Kconfig option (Hans)
- Updated Kconfig dependencies with COMPILE_TEST, now depends on SOC_DRA7XX || COMPILE_TEST (Hans)
- In vip_s_std(), moved the standard validation check before the vb2_is_busy() check (Hans)
- In vip_s_fmt_vid_cap(), moved the vip_try_fmt_vid_cap() call before the vb2_is_busy() check (Hans)
- Put all vip_set_slice_path() calls on a single line for better readability (Hans)
- Clean up set_fmt_params and unset_fmt_params functions to make the logic easier to read (Hans)
- Add a vb2_is_busy check in vip_s_selection (Hans)
- Remove buffer count check in vip_queue_setup (Hans)
- For *nplanes is != 0 just check the size in vip_queue_setup (Hans)
- Remove read support (Hans)
- Change vip_register_subdev_notif() to vip_register_subdev_notify() (Hans)
- Also fixed issues reported by Coccinelle and W=1 build.
