Add new bindings for the v2 Marvell xSPI overlay: marvell,cn10-xspi-nor compatible string. This new compatible string distinguishes between the original and modified xSPI block. Also add an optional base for the xfer register set with an additional reg field to allocate the xSPI Marvell overlay XFER block.
