Add Uart to STM32F4Discovery and rework uart-sync example (#43)
* stm32f407: add Uart support

* lpc1768: add cpu_frequency in board and chip

Allow using them with microzig Uart, which ensures the clock is present

* lpc1768: fix UART2 and UART3 peripheral clock register

They are in the PCLKSEL1 register, not PCLKSEL0

* uart-sync: use native microzig Uart, target different boards/chips

The previous example was lpc1768 specific, this new example should work with all
board and chips which implement the microzig Uart functionality. Instead of 4
LEDs, the new example uses a single LED to provide minimal debugging
capabilities if something does not work correctly.
This allows building this example for the stm32 f3 and f4 discovery boards.
