Subject: [PATCH 1/3] media: doc: pixfmt-yuv: Fix V4L2-PIX-FMT-Y10P format

This packed grey-scale image format has a depth of 10 bits per pixel.
Every four consecutive pixels are packed into 5 bytes. Each of the first
4 bytes contain the 8 high order bits of the pixels, and the 5th byte
contains the 2 least significants bits of each pixel, in the same order.

The first two bytes are not corresponding to this description, fix it.
