Change rounding to the minimal burst size from 2^n to n.
This fixes images with sizes that are a multiple of 8 pixels.
See section 13.7.6.13 CSI Image Parameter Register of the
i.MX 8M Quad Applications Processors Reference Manual.
Fixes: 451a7b7815d0b ("media: imx: lift CSI and PRP ENC/VF width
alignment restriction")
