clk: rockchip: rk3308: Support reading UART rate and clock registers
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).
