[v2,6/9] net: ethernet: ti: am65-cpsw: Convert to devm_of_phy_optional_get()

Use the new devm_of_phy_optional_get() helper instead of open-coding the
same operation.

v2:
  - Rebase on top of commit 854617f52ab42418 ("net: ethernet: ti:
    am65-cpsw: Handle -EPROBE_DEFER for Serdes PHY") in net-next
    (next-20230123 and later).
