regulator: cpr-regulator: add support for fuse bit remapping

On certain targets some fuse parameters are split between
non-contiguous fuse rows.  The various device tree fuse
specification properties cannot handle such a layout.  Therefore,
add support for a pair of device tree properties which can be
used to remap arbitrary combinations of fuse bits into a single
contiguous range of virtual fuse rows.  These remapped fuse rows
can then be referenced by all other device tree fuse properties.
