10 This reverts commit 45aefe3d2251e4e229d7662052739f96ad1d08d9.
11
12 Armada 3720 PHY driver (phy-mvebu-a3700-comphy.c) does not return
13 -EOPNOTSUPP from phy_power_on() callback anymore.
14
15 So remove AHCI_HFLAG_IGN_NOTSUPP_POWER_ON flag from Armada 3720 plat data.
16
17 AHCI_HFLAG_IGN_NOTSUPP_POWER_ON is not used by any other ahci driver, so
18 remove this flag completely.
