[PATCH 0/3] Add device DM163 (led driver, matrix colors shield & display)

["Inès Varhol" <ines.varhol@telecom-paris.fr>]

This device implements the IM120417002 colors shield v1.1 for Arduino
(which relies on the DM163 8x3-channel led driving logic) and features
a simple display of an 8x8 RGB matrix.

This color shield can be plugged on the Arduino board (or the
B-L475E-IOT01A board) to drive an 8x8 RGB led matrix.
This RGB led matrix takes advantage of retinal persistance to
seemingly display different colors in each row.

It'd be convenient to set the QEMU console's refresh rate
in order to ensure that the delay before turning off rows
(2 frames currently) isn't too short. However
`dpy_ui_info_supported(s->console)` can't be used.

I saw that Kconfig configurable components aren't visible in C files,
does that mean it's impossible to make the DM163 device optional when
using the B-L475E-IOT01A board?
