spi: spi-mem: add stm32 qspi controller
The qspi controller is a specialized communication interface
targeting single, dual or quad SPI Flash memories (NOR/NAND).
It can operate in any of the following modes:
-indirect mode: all the operations are performed using the quadspi
registers
-read memory-mapped mode: the external Flash memory is mapped to the
microcontroller address space and is seen by the system as if it was
an internal memory
tested on:
-NOR: mx66l51235l
-NAND: MT29F2G01ABAGD
