* fix case-sensitivity issues on MIDI_ENABLE

Change instances of `MIDI_ENABLE = YES` to `MIDI_ENABLE = yes`.

Command:

```
find keyboards/ -type f -name 'rules.mk' -and -not -path '*/keymaps/*' -exec sed -i -e 's;MIDI_ENABLE[ \t]*=[ \t]*[Yy][Ee][Ss];MIDI_ENABLE = yes;g' {} +
```

* replace `# MIDI controls` with `# MIDI support`

Replace `# MIDI controls` with `# MIDI support` in keyboard-level `rules.mk` files.
