riscv: dts: spacemit: Acquire clocks for UART

Browse source

The K1 SoC features two clocks for UART controller, Acquire them
explicitly in the driver. Also it is required to remove the
clock-frequency properties from the uart node, otherwise the new
clock properties are ignored by of_platform_serial_setup() in "8250_of.c".
