* Support the Clara B&W, Clara Colour & Libra Colour
* Enable HW dithering on *all* the Kobo MTK devices
* Enforce 32bpp instead of 8bpp for Kobo devices with a color panel (the driver doesn't actually support 8bpp anyway)
* Enable standby support on MTK (whenever possible, i.e., not when plugged in, as that is horribly, horribly broken).
* Enforce the dedicated "color" waveform mode for image content in ScreenSaver, ImageViewer & Reader.
* Fix charging LED support on MTK
* Tweak the frontlight ramp on MTK + LM3630 so that it actually ramps smoothly
