Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

This patch adds basic support and documentation for the STM32F723E-DISCO
board, with GPIO, USART, I2C and USB support. Two USARTs are enabled,
the VCP one for the console and the Arduino one. The GPIOs are
configured for the 3 LEDs and the button available on the board.
