[media] bcm2048: add TODO file for this staging driver

Describe the tasks to be done for this driver to be promoted to a
non-staging one.

[m.chehab@samsung.com: Add a patch description; add a note about the
 CodingStyle issues and make sure that the README lines are not bigger
 than 80 cols.]

+TODO:
+
+From the initial code review:
+
+The main thing you need to do is to implement all the controls using the
+control framework (see Documentation/video4linux/v4l2-controls.txt).
+Most drivers are by now converted to the control framework, so you will
+find many examples of how to do this in drivers/media/radio.
+
+The sysfs stuff should be replaced by controls as well. A lot of the RDS
+support is now available as controls (although there may well be some
+missing features, but that is easy enough to add). Since the RDS data is
+actually read() from the device I am not sure whether the RDS
+properties/controls should be there at all.
+
+Correct Coding Style, as this driver also violates several Style
+rules, and do evil tricks, like returning from a function inside a
+macro.
+
+Finally this driver should probably be split up into two parts: one
+v4l2_subdev-based core driver and one platform driver. See e.g.
+radio-si4713/si4713-i2c.c as a good example. But I would wait with that
+until the rest of the driver is cleaned up. Then I have a better idea of
+whether this is necessary or not.
