Subject: [PATCH v4 0/7] Add some enhancements for i.MX95 PCIe

v4 changes:
- Add another patch to skip one dw_pcie_wait_for_link() in the workaround link
  training refer to Mani' suggestion.
- Rephrase the comments in "PCI: imx6: Toggle the cold reset for i.MX95 PCIe".
- Correct the error return in "PCI: imx6: Add PLL clock lock check for i.MX95 PCIe".
- Collect and add the Reviewd-by tags.

v3 changes:
- Correct the typo error in first patch, and update the commit message of
  #1 and #6 pathes.
- Use a quirk flag to specify the errata workaround contained in post_init.

v2 changes:
- Correct typo error, and update commit message.
- Replace regmap_update_bits() by regmap_set_bits/regmap_clear_bits.
- Use post_init callback of dw_pcie_host_ops.
- Add one more PLL lock check patch.
- Reformat LUT save and restore functions.
