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](http://dfu-util.sourceforge.net/) or
|
||||
[pydfu.py](https://github.com/micropython/micropython/blob/master/tools/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.
|
||||
|
||||
```bash
|
||||
dfu-util --alt 0 -D firmware.dfu
|
||||
```
