Tegra EMC driver was turned into a regular kernel driver, it also could
be compiled as a loadable kernel module now. Hence EMC clock isn't
guaranteed to be available and clk_get("emc") may return -EPROBE_DEFER and
there is no good reason to spam KMSG with a error about missing EMC clock
in this case, so let's silence the deferred probe error.
