ipa: raspberrypi: Add functional include to pwl.h

Browse source 
The Pwl class uses std::function, defined in <functional>, without
including the header directly. This results in a compilation error with
the Fedora 36 compiler toolchain (gcc 12.1.1):

In file included from ../src/ipa/raspberrypi/controller/rpi/awb.h:14,
                 from ../src/ipa/raspberrypi/controller/rpi/awb.cpp:14:
../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;
      |                  ^~~

Fix it by including <functional>.
