Fix Crema Soundup menu flickering due to unsupported GLR16 waveform (#582)

The Crema Soundup was using TolinoEPDController, which uses the GLR16
waveform for UI refreshes. The Crema Soundup firmware does not properly
support GLR16, causing menu popups to flicker and turn white.

Add a dedicated CremaEPDController that uses GC16 for UI refreshes
instead of GLR16.
