nvmem: zynqmp_nvmem: unbreak driver after cleanup

Commit 29be47f ("nvmem: zynqmp_nvmem: zynqmp_nvmem_probe cleanup")
changed the driver to expect the device pointer to be passed as the
"context", but in nvmem the context parameter comes from nvmem_config.priv
which is never set - Leading to null pointer exceptions when the device is
accessed.
