arch: arm: dts: k3-j721s2-r5: Override ospi and fss for 32-bit mode

R5 being a 32-bit processor can't understand the 64-bit mapping being
done in ospi node. Override the ospi node for 32-bit register ranges and
the fss node ( the parent node of ospi ) to map the ranges for the
updated child node correctly.
