Thanks for this! When I initially created panel.c about 20 years ago
I didn't even realize there was a miscdevice.h to centralize all this.
It's definitely cleaner this way.

So I've built for ARM to check, I could enable and successfully build
these modules that you touched: charlcd, panel, applicom, devsynth,
speakup_soft. The other ones might require less obvious configs to be
build-tested.
