[PATCH] drivers: media: i2c: imx335: Fix frame size enumeration

[Kieran Bingham <kieran.bingham@ideasonboard.com>]

In commit cfa49ff0558a ("media: i2c: imx335: Support 2592x1940 10-bit
mode") the IMX335 driver was extended to support multiple output
bitdepth modes.

This incorrectly extended the frame size enumeration to check against
the supported mbus_codes array instead of the supported mode/frame
array. This has the unwanted side effect of reporting the currently
supported frame size 2592x1944 three times.

Fix the check accordingly to report a frame size for each supported
size, which is presently only a single entry.

Fixes: cfa49ff0558a ("media: i2c: imx335: Support 2592x1940 10-bit mode")

I expect to post a 2/2 binning mode series on top of this later to then
further extend the supported_mode into an array ...

So I won't dwell on tracking fsize->index against the 'size' or number
of supported modes yet... but this fixes an otherwise annoying glitch
;-)
