DSP: Remove all mentions of the mysterious DROM. Write protect the ROMs and IRAM as much as possible while loaded (to make sure they don't get corrupted by some memory overwrite or whatever). Make instruction reads stricter - iram and irom don't wrap anymore (not 100% sure about this one). Misc cleanup + changes.
