net: phy: dp83867: fix get nvmem cell fail
If CONFIG_NVMEM is not set of_nvmem_cell_get, of_nvmem_device_get
functions will return ERR_PTR(-EOPNOTSUPP) and "failed to get nvmem
cell io_impedance_ctrl" error would be reported despite "io_impedance_ctrl"
is completely missing in Device Tree and we should use default values.
Check -EOPNOTSUPP togather with -ENOENT to avoid this situation.
