serial: tegra: Don't print error on probe deferral
If the Tegra serial driver is probe before clocks are available then the
following error is seen on boot:
serial-tegra 3100000.serial: Couldn't get the clock
This has been observed on Jetson AGX Orin. Fix this by calling
dev_err_probe() instead of dev_err() to avoid printing an error on probe
deferral.
