Added arduino-nano to BOARD_INSUFFICIENT_MEMORY/BOARD_BLACKLIST following suit
of how arduino-uno is marked, as arduino-nano is mostly an Uno in a different
form factor.
The Arduino Nano board is the cheapest member of the Arduino family and used the
same MCU as the Arduino Uno. It differs in the form factor (the Nano is much
smaller), it uses an integrated FT232RL TTL adapter instead of an ATmega16u2 to
provide access to the serial console via USB, and it uses a different
bootloader (which occupies 2 KiB of the 32 KiB flash instead of 0.5 KiB occupied
on the Arduino Uno). This commit mostly copy pastes code from the Arduino Uno.
Linkerscript for `nrf52dk` has been updated to use `cortexm.ld` so does
not need the configuration anymore for the removed
`cpu/nrf52/ldscripts/nrf52832xxaa.ld`.
Add motor_driver driver configuration example.
The most simple motor driver type is used here (MOTOR_DRIVER_1_DIR) which
needs only one pin to work.
This example uses already configured PWM channels and 2 free GPIOS.

Test motor_driver API by making 2 motors turn clockwise and
counter-clockwise alternatively.
Speed varies from 0 to max PWM duty cycle.

Configure 2 factice motors in one motor_driver.
native_motor_driver_qdec_simulation() is provided to simulate QDEC encoders
virtually linked to the motors.

native_motor_driver_qdec_simulation() callback is called each time
motor_set() from motor_driver driver is called.
It set associated qdec value to the PWM duty cycle.
QDEC values are stored in qdecs_value[] array in the order motors
are described in board.h.
Then it is needed to configure in first motors that needs the QDEC in
board.h.

If the GPIO is in an output state, gpio_init() can return 0 without bad
consequences.
-1 was return until now.

This driver API aims to control DC motors.
It handles :
* motor controller associated to a PWM device
* several motors by controller
* motor rotation direction
* brake capability
* enable/disable motor individually

If module log is used, log.h should be included. Otherwise, it might lead to compilation problems since LOG_ERROR macro isn't know in expansion of LWIP_PLATFORM_ASSERT macro.
