The PHY sits behind a GDSC, so also allow (and require) power-domains for it. The block gets a standalone compatible rather than a fallback to an existing one, because it is not register-compatible with any PHY already described here. Its USB3 and DP initialisation sequences do match sm8550, but Nord places the sub-blocks at different offsets within the PHY: it exposes a dedicated USB3_PCS_AON region at 0x1e00, which sm8550 does not have at all. Falling back to sm8550 - or to any other entry - would make the driver program the wrong addresses.
