[PATCH v2 1/2] PCI: tegra194: Use dev_err_probe() for PERST# GPIO

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

Use dev_err_probe() when getting the PERST# GPIO to simplify error
handling and properly handle -EPROBE_DEFER.

Changes in v2:
 - Follow the subject line capitalization style.
 - Use "PERST#" in the subject, commit log, and dmesg text to match
   spec usage.
