Added hardware defines for stm32h5_qspi driver and octospi GPIOs (used by stm32h5_qspi driver).

Add commit log to OCTOSPI HW PR

Summary

hardware/stm32_qspi.h - Defines for the STM32H5 QSPI driver. The peripheral on the STM32H5 is actually an OCTOSPI peripheral, however it was decided to use it as a QSPI peripheral for the following reasons:

    There is currently support for QSPI within Nuttx.
    The STM32H7 QSPI register set is very similar to the STM32H5 OCTOSPI register set and the STM32H7 series has an existing QSPI driver.
    OCTOSPI devices are rare as of now and are not part of our use case.

hardware/stm32h56xxx_pinmap.h - Added pin mappings for OCTOSPI GPIOs.
Impact

This change will not impact any architectures outside of the STM32H5 series. Even for the STM32H5 series, these changes will only have an impact if they are utilized.
Testing

No testing yet for these files other than ensuring that we can still build Nuttx. Further testing will be documented in a future pull request when the STM32H5 QSPI driver is added.
