Why not simply drop the second register range here, and the minimal top-ctrl poking you need in the phy driver's phy_init function ?
This avoids the weird / ugly register overlap with the phy driver, and I think you can then just use the ahci_platform driver unmodified.

Why not simply use: reg = <0x458000 0x2000>, to me it seems that what you should really be using here.
