[PATCH v8 12/26] memory: tegra124-emc: Continue probing if timings are missing in device-tree

[Dmitry Osipenko]

EMC driver will become mandatory after turning it into interconnect
provider because interconnect users, like display controller driver, will
fail to probe using newer device-trees that have interconnect properties.
Thus make EMC driver to probe even if timings are missing in device-tree.
