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. The columns of the matrix are
driven by the DM163 and the rows are driven externally.

Exposing SYSCFG inputs to the SoC is practical in order to wire the SoC
to the optional DM163 display from the board code (GPIOs outputs need
to be connected to both SYSCFG inputs and DM163 inputs).
STM32L4x5 SYSCFG in-irq interception needed to be changed accordingly.

`test_dm163_bank()`
Checks that the pin "sout" of the DM163 led driver outputs the values
received on pin "sin" with the expected latency (depending on the bank).
`test_dm163_gpio_connection()`
Check that changes to relevant STM32L4x5 GPIO pins are propagated to the
DM163 device.
