Subject: [PATCH v2 1/4] media: sun6i-csi: Fix the bpp for 10-bit bayer formats

10-bit bayer formats are aligned to 16 bits in memory, so this is what
needs to be used as bpp for calculating the size of the buffers to
allocate.
This function is only used to generate the number of bytes per line.

Fixes: 5cc7522d8965 ("media: sun6i: Add support for Allwinner CSI V3s")
