* spi_mem_supports_op() - Check if a memory device and the controller it is

* @op: the memory operation to check
*
* Some controllers are only supporting Single or Dual IOs, others might only
* support specific opcodes, or it can even be that the controller and device
* both support Quad IOs but the hardware prevents you from using it because
* only 2 IO lines are connected.
*
* This function checks whether a specific operation is supported.
