spi: spi-mem: add spi_mem_adjust_op_freq() in spi_mem_supports_op()
The function spi_mem_adjust_op_freq() within spi_mem_exec_op() adjusts
the op->max_freq, which will informs the SPI controller of the maximum
frequency for each operation. This adjustment is based on combined
information from the SPI device and the board's wiring conditions.
Similarly, spi_mem_supports_op() will check the capabilities of the SPI
controller. It also requires the combined information before it can
accurately determine whether the SPI controller supports a given operation.
