Subject: [PATCH v2 4/9] net: fman: memac: Convert to devm_of_phy_optional_get()

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

As devm_of_phy_optional_get() returns NULL if either the PHY cannot be
found, or if support for the PHY framework is not enabled, it is no
longer needed to check for -ENODEV or -ENOSYS.

Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>
Reviewed-by: Sean Anderson <sean.anderson@...o.com>
---
v2:
  - Add Reviewed-by,
  - Clarify removed checks for -ENODEV and -ENOSYS,
  - Remove error printing in case of real failures.
