Looking at the code this is already implemented. It already creates the
reg property using of_write_number() and honouring of_n_addr_cells() /
of_n_size_cells(). This of course only works when the target device tree
already has the #address-cells and #size-cells properties with the
correct values. So instead of just setting them to hardcoded '1' you
should set them to the desired value, the loop below should do the rest

The partitions subnode was introduced with 4.4, so we better do not rely
on the kernel being able to handle it.
What we can and probably should do is to look into the target device tree
if it already has a partitions subnode with compatible = "fixed-partitions"
and if does, use it.
