[PATCH v6 5/5] libcamera: software_isp: Remove TODO about internal representation

[Milan Zamazal]

TODO #4 was recorded at a time where the IPA module computed gain values
and the ISP computed the look up tables.  The gains were higher-level
parameters.  Now that the look up tables are computed in the IPA module,
the IPA and ISP are more tightly coupled and the TODO item is less
relevant.

Let's drop the TODO item.  We may or may not need to switch to a
different representation in future but there is currently no good need
for this and the conversion of the values would be just waste of CPU
cycles.

-4. Hide internal representation of gains from callers

-Forcing the caller to deal with the internal representation of gains
-isn't nice, especially given that it precludes implementing gains of
-different precisions in different backend. Wouldn't it be better to pass
-the values as floating point numbers, and convert them to the internal
-representation in the implementation of process() before using them ?
