Series-changes: 7
- s/strlcpy/strscpy
- Fix v4l2-compliance issues:
	* remove input ioctls
media api can be used to define the topology, this input api is not
required. Besides it, if an input is enumerated, v4l2-compliance is not
happy with G_FMT returning the default colorspace instead of something
more specific.
	* return the pixelformat to the userspace
G_/S_/TRY_ FORMAT should return a valid pixelformat to the user, even if
the user gave an invalid one
	* add missing default colorspace and ycbcr
	* fix wrong pixformat in mp_fmts[] table
	* add buf type check in s_/g_selection
	* queue_setup - check sizes
	* normalize bus_info name
	* fix field any v4l2-compliance -s complain - set field none
	when streaming
- Fix compiling error: s/vidioc_enum_fmt_vid_cap_mplane/vidioc_enum_fmt_vid_cap
- Replace stream state with a boolean
The rkisp1_state enum consists only of 3 entries, where 1 is completely
unused and the other two respectively mean not streaming or streaming.
Replace it with a boolean called "streaming".
- Simplify MI interrupt handling
Rather than adding unnecessary indirection, just use stream index to
handle MI interrupt enable/disable/clear, since the stream index matches
the order of bits now, thanks to previous patch. While at it, remove
some dead code.
- code styling and checkpatch fixes
- add link_validate: don't allow a link with bayer/non-bayer mismatch
