versal: patch enables xilnvm and xilpuf in the PLM
Adding in the PetaLinux patch that enables XilNvm and XilPuf drivers in the PLM,
which is required by the Versal OP-TEE port. Additionally, updated the BIF file
to point to the updated PLM instead of the pre-built PLM.
This update goes along with the document update:
https://github.com/OP-TEE/optee_docs/pull/209.
