As discussed on the media summit 2013, there is no reason for the width
and height to be signed.
Therefore this patch is an attempt to convert those fields from __s32 to
__u32.

internal_csi_format_idx and csi_format_idx are unsigned integers,
therefore they can never be nevative.

As the clock framework makes it possible to assign a device specific name to
the clocks, remove the ability to use a named clock in the driver.

Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.
Similarly probe() methods should not be marked __init unless
platform_driver_probe() is used.

The format shown on the links internal to the sensor was the first one
enumerated from the sensor, not the highest bit depth data that can be
produced by the sensor. Correct this.
