[libcamera-devel] [PATCH] ipa: raspberrypi: Fix compiler error, add functional include

[Eric Curtin]

gcc version '12.1.1 20220507 (Red Hat 12.1.1-1)' fails with the
following error on Fedora 36. This file should include the functional
header as it uses std::function.

In file included from ../src/ipa/raspberrypi/controller/rpi/ccm.h:12,
                 from ../src/ipa/raspberrypi/controller/rpi/ccm.cpp:15:
../src/ipa/raspberrypi/controller/rpi/../pwl.h:97:18: error: ‘std::function’ has not been declared
   97 |         void map(std::function<void(double x, double y)> f) const;
