phy: qcom-snps: Use dev_err_probe() to simplify code

Browse Source 
[ Upstream commit 668dc8afce43d4bc01feb3e929d6d5ffcb14f899 ]

In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER and prints the
error name. It also sets the defer probe reason which can be
checked later through debugfs.
