[Richard Zhu]

Based on previous review patch-set [1] and no function changes, create
one update for the last patch only after merge the comments provided
by Krzysztof.
- Clean up codes. Drop the redundant inner break, and use the dev_err_probe
  replace dev_err in _probe().
- To be consistent, let the error message to be all lower-case letters.
- Add one comment to explain that there is one single bare break for
  i.MX8MM in imx6_pcie_init_phy()
