The xc3028 version does i2c splitting in a different manner than xc4000 and
xc5000, so reuse the xc5000 version of the routine (the key here being that
xc4000 expects the first *two* bytes to be the same for splitting transactions.

Doing it the xc3028 way was resulting in i2c errors partially through the
firmware load.  With this change, it would appear that the entire base firmware
is being loaded successfully (product id now properly shows 0x0FA0).

The implementation of the gain calculation for this sensor is incorrect.
It is only working for the first 127 values.

The reason is, that the gain cannot be set directly by writing a value
into the gain registers of the sensor. The gain register work this way
(see datasheet page 24): bits 0 to 6 are called "initial gain". These
are linear. But bits 7 and 8 ("analog multiplicative factors") and bits
9 and 10 ("digital multiplicative factors") work completely different:
Each of these bits increase the gain by the factor 2. So if the bits
7-10 are 0011, 0110, 1100 or 0101 for example, the gain from bits 0-6 is
multiplied by 4. The order of the bits 7-10 is not important for the
resulting gain. (But there are some recommended values for low noise)

The current driver doesn't do this correctly: If the current gain is 000
0111 1111 (127) and the gain is increased by 1, you would expect the
image to become brighter. But the image is completly dark, because the
new gain is 000 1000 0000 (128). This means: Initial gain of 0,
multiplied by 2. The result is 0.

This patch adds a new function which does the gain calculation and also
fixes the same bug for red_balance and blue_balance. Additionally, the
driver follows the recommendation from the datasheet, which says, that
the gain should always be above 0x0020.

There are problems when you use this camera/sensor in a very bright room
or outside. The image is completely white, because it is overexposed.
The driver uses a default value which is not suitable for all
environments.

This patch makes it possible to adjust the exposure time by youself. I
found out by logging the i2c-data, that the windows driver for this
sensor is doing this, too. I tested the camera on a sunny day and after
adjusting the exposure time, I was able to see a very good image.
