yinshengkai 1d8e69700f drivers/serial: add ram uart driver
It uses the memory block as the serial communication medium, which can communicate between different processes or different CPUs

Using the following configuration, the cross-core communication rate of 200MHz cortex-M55 is about 461KB/s
RAM_UART_BUFSIZE=1024
RAM_UART_POLLING_INTERVAL=100
