serial: mvebu-uart: add function to change baudrate Until now, the first UART port baudrate was set by the bootloader. Add a function allowing to change the baudrate. Changes may be done from userspace but also at probe time by the kernel. Use the simplest method: baudrate divisor. Works for all UART ports until 230400 baud. To achieve higher baudrates, software should implement the fractional divisor feature that allows more accuracy for higher rates.
