hw/display : Add device DM163

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.

hw/gpio: Implement STM32L4x5 GPIO

Features supported :
- the 8 STM32L4x5 GPIOs are initialized with their reset values
(except IDR, see below)
- input mode : setting a pin in input mode "externally" (using input
irqs) results in an out irq (transmitted to SYSCFG)
- output mode : setting a bit in ODR sets the corresponding out irq
(if this line is configured in output mode)
- pull-up, pull-down
- push-pull, open-drain

Difference with the real GPIOs :
- Alternate Function and Analog mode aren't implemented :
pins in AF/Analog behave like pins in input mode
- floating pins stay at their last value
- register IDR reset values differ from the real one :
values are coherent with the other registers reset values
and the fact that AF/Analog modes aren't implemented
- setting I/O output speed isn't supported
- locking port bits isn't supported
- ADC function isn't supported
- GPIOH has 16 pins instead of 2 pins
- writing to registers LCKR, AFRL, AFRH and ASCR is ineffective

Add the necessary files to add a simple RCC implementation with just
reads from and writes to registers. Also instantiate the RCC in the
STM32L4x5_SoC. It is needed for accurate emulation of all the SoC
clocks and timers.
