spi: cadence_qspi: Migrate CONFIG_CQSPI_REF_CLK to Kconfig
This is a little tricky since SoCFPGA has code to determine this as
runtime. Introduce a guard variable for platforms to select if they
have a static value to use. Then for ARCH_SOCFPGA, call
cm_get_qspi_controller_clk_hz() and otherwise continue the previous
behavior.
