#98619 introduced the flash extended operation API to allow other drivers to read/write arbitrary commands to the flash part. This PR implements that API for this driver.
Testing
Tested using nRF54H with Gigadevice GD25LE64E flash part connected to the MSPI bus. Was able to send arbitary commands to the flash part to implement more vendor-specific functionalty like write-protect using this driver as the base.
Waiting for an RFC on this first: #98619
