Currently, Berlin SATA PHY driver assumes PHY_BASE address being
constant. While this PHY_BASE is correct for BG2Q, older BG2 PHY_BASE
is different. Prepare the driver for BG2 support by moving the phy_base
into private driver data.

Can't the base directly come from dt?

You are suggesting a "marvell,phy-base-address" property, right?
I have no strong opinion about it, I accept your call (or DT maintainer
ones).
