Use dev_err_probe() in tegra114_emc_interconnect_init() to make code a
bit simpler. It's preferred form of printing error messages during
probe, even if actual call cannot return EPROBE_DEFER.

memory: tegra: Fix possible null pointer dereference
The function tegra114_emc_find_timing() has the possibility of returning
null and it's return value 'timing' is dereferenced before it is
checked for null.
Place dereference after null pointer check.
Detected by Smatch:
drivers/memory/tegra/tegra114-emc.c:520 tegra114_emc_prepare_timing_change()
warn: variable dereferenced before check 'timing' (see line 515)
