Add support to read RK3308 registers used to configure UART clocks, and thus to get UART rate and baudrate. This fixes clock_get_rate returning error on serial device probing. Moreover, there is no need anymore to use 'clock-frequency' property for UART nodes in *-u-boot.dtsi files for all cases where UART is not inited by U-Boot proper or by SPL o by TPL code but by a preliminary external boot phase (for Rock PI S, UART is inited by external TPL).
