[PATCH phy v4 5/5] Revert "PCI: aardvark: Fix initialization with old Marvell's Arm Trusted Firmware"

[Marek Behún]

From: Pali Rohár <pali@kernel.org>

This reverts commit b0c6ae0f8948a2be6bf4e8b4bbab9ca1343289b6.

Armada 3720 phy driver (phy-mvebu-a3700-comphy.c) does not return
-EOPNOTSUPP from phy_power_on() callback anymore.

So remove dead code which handles -EOPNOTSUPP return value.

Dear Lorenzo,

could you please give your Ack for this, so that Vinod can apply it
with the rest of the comphy series?
The series can be found at
