spi: zynq_qspi: Use clk subsystem to get reference qspi clk

Remove fixed reference clk used by plat->frequency and use clk
subsystem to get reference clk. As per spi dt bindings
"spi-max-frequency" property should be used by the slave devices.
This property is read by spi-uclass driver for the slave device.
So avoid reading above property from the platform driver.
