nvmem: zynqmp_nvmem: unbreak driver after cleanup

Browse Source 
commit fe8abdd175d7b547ae1a612757e7902bcd62e9cf upstream.

Commit 29be47fcd6 ("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.

Fixes: 29be47fcd6 ("nvmem: zynqmp_nvmem: zynqmp_nvmem_probe cleanup")
