Add support for flash NOR memory devices on a NXP S32 QSPI bus. The driver uses a fixed LUT configuration assuming a default standard page size and erase types, and allows to select between multiple read/program instructions/modes. It is also possible to read the flash device characteristics from the device at run-time as long as the memory is JESD216 compatible, providing more flexibility.
