Lorenzo Cappelletti 8f0e304e65 stm32/boards: Add new board MikroElektronika Quail, and F427 support. 
Quail (https://www.mikroe.com/quail, PID: MIKROE-1793) is based on an
STM32F427VI CPU, featuring 2048 kB of Flash memory and 192 kB of RAM.  An
on-board Cypress S25FL164K adds 8 MB of SPI Flash.

Quail has 4 mikroBUS(TM) sockets for Mikroe click(TM) board connectivity,
along with 24 screw terminals for connecting additional electronics and two
USB ports (one for programming, the other for external mass storage).

4 UARTs, 2 SPIs and 1 I2C bus are available for communication.

Quail via DFU

Quail can be programmed via USB with the ST DFU bootloader, using e.g. dfu-util or pydfu.py.

To enter the bootloader press and release the Reset button while holding the Boot button. Alternatively, you can use machine.bootloader() from the MicroPython REPL.
