bsps/stm32h7: allow config and usage of QSPI memory on stm32h757i-eval BSP

The QSPI memory is initialized and used only when the BSP configure file
sets QSPI memory size to non-zero value. Currently QSPI is run in memory
mapped mode which allows future RTEMS binary linkage and upload into QSPI
memory.
