When the arbitration between NOR and NAND flash is enabled
the <FORCE_CSX> field bit[21] in the Data Flash Control Register
needs to be set to 1 according to guidleine GL-5830741.

This patch introduces a new compatible string "marvell,nand-force-csx"
which is activated through device tree to implement the guideline
GL-5830741.
