This reverts commit 45aefe3d.

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

So remove AHCI_HFLAG_IGN_NOTSUPP_POWER_ON flag from Armada 3720 plat data.

AHCI_HFLAG_IGN_NOTSUPP_POWER_ON is not used by any other ahci driver, so
remove this flag completely.
