Generalise the contrast algorithm code by removing any hard-coded assumptions about the target hardware platform. Instead, the algorithm code creates a generic Pwl that gets returned to the IPA, where it gets converted to the bcm2835 hardware specific lookup table. As a drive-by, remove an unused mutex.
