Add driver for CMSDK APB UART ports. The driver implements RX and TX functionalities. Data transmission is implemented using polling and interrupts. The driver default configuration for the port is to use 8bit data transmission, 1 stop bit, no parity control. The driver exposes a public uart driver API and allows to register up to five UART devices: from 'UART_0' to 'UART_4'. The driver performs the required pinmux, the clock control configuration is left to the platform. The driver has been verified to work with the Hello World sample application on a Beetle Board.
