ARM: dts: rockchip: Remove unnecessary setting of UART0 SCLK rate on veyron
Some veyron devices have a Bluetooth controller connected on UART0. The UART needs to operate at a high speed, however setting the clock rate at initialization has no practical effect. During initialization user space adjusts the UART baudrate multiple times, which ends up changing the SCLK rate. After a successful initiatalization the clk is running at the desired speed (48MHz). Remove the unnecessary clock rate configuration from the DT.
