spi: stm32: Add OSPI driver 



Add STM32 OSPI driver, it supports :
  - support sNOR / sNAND devices.
  - Three functional modes: indirect, automatic-status polling,
    memory-mapped.
  - Single-, dual-, quad-, and octal-SPI communication.
  - Dual-quad communication.
  - Single data rate (SDR).
  - DMA channel for indirect mode.
