[ARM] pxa/mioa701: fix camera regression

Since commit a48c24a, the
camera is not working anymore.

After the v4l2 migration, the mt9m111 camera board
information was not passed to the i2c layer anymore, but
stored for future use of v4l2 (through soc_camera).

Because mioa701_i2c_devices[] was tagged as "__initdata",
and because after the v4l2 migration, the new structure
"iclink" references it, the mt9m111 driver is not probed
anymore, as part of "iclink" is not valid (discarded after
kernel init).

Although there is not compilation error, nor runtime oops,
this patch restores a working camera on the mioa701 board.
