[U-Boot] [PATCH v6 1/2] SOCFPGA: clock manager: implement dw_spi_get_clk function

Implement dw_spi_get_clk function to override its weak
implementation in designware_spi.c driver.

We need this change to get rid of cm_get_spi_controller_clk_hz
function and clock_manager.h include in designware_spi.c driver.
