Add QSPI support for K3 in DT and board config, and update
fsl_qspi to handle the clocks required by the controller.

Please do not submit a Pull Request via github. Our project makes use of
mailing lists for patch submission and review. For more details please
see https://u-boot.readthedocs.io/en/latest/develop/sending_patches.html

The only exception to this is in order to trigger a CI loop on Azure prior
to posting of patches.
