8fcfc44c15 video: Add a helper to get the tile size information
Since the addition of tiling format with subsampled tile size
(NV12_16L32S), getting the tile width/height shifts and tile
size have become more complex. Add a helper to extract and
scale this information for the selected plane and format.

Fix 2 iterations that can overrun the array if the number of component is
equal to the size of the array.

094d121812 video: Add support for linear 8x128 NV12 tiles and 10bit BE tiles
This adds linear 8x128 NV12 based tiles and NV12 10bit big endian tiles.
These formats are used by i.MX 8QXP/8QM VPU and exposed in V4L2.

fa1f042d1d video: Add an helper to extrapolate strides
Many of the legacy APIs, specifically in the Linux Kernel, have a
single stride for the pictures. In this context, it is common
to extrapolate the other strides based on the selected pixel
format. Such function have been copy pasted from video4linux2
plugin into wayland, kms and v4l2codecs plugins.

This patch implements a generalized from of that function and
make it available to everyone through the video library.

c9b127dae3 video: Add NV12_16L32S aka Mediatek MM21 support
Unlike other simple tiled formats, the Mediatek HW use different tile size
per-plane. The tile size is scaled according to the subsampling. Effectively,
using the name 16L32S to represent linearly layout tiles of size 16x32 bytes
in the Y plane, and 16x16 in the UV plane. In order to make this specificity
discoverable, a new SUBTILES flags have been added.
