sata_mv: revert SoC irq breakage
Revert most of commit 6be96ac1d5e4d913e1f48299db083ada5321803b2, originally from Lennert Buijtenheck (Marvell) and Saeed Bishara (Marvell), since that commit causes sata_mv to oops at startup on SOC "Kirkwood". The SOC variants do not have the hpriv->irq_{cause,mask}_ofs registers, so don't try to write to them! This patch should also be considered for -stable.
