[PATCH 1/3] media: imx: imx7-media-csi: Move variable to loop scope

[Laurent Pinchart <laurent.pinchart@ideasonboard.com>]

The phys variable is only used as a local loop variable in
imx7_csi_setup_vb2_buf(), with each entry in the array being used in the
corresponding iteration of the loop only. Move it to loop scope,
simplifying the array to a single variable.
