libfdt: Simplify adjustment of values for local fixups

In a couple of places in fdt_overlay.c we need to adjust a phandle value
in a property (either a node's phandle itself or a reference) by some
delta.  Currently this is done if a fairly convoluted way, open-coding
loading the value and handling of a non-aligned reference, and then using
fdt_setprop_inplace_partial() to replace the value.  This becomes much
simpler if we use fdt_getprop_w() to get a writable pointer to the value
then we can just load/store it with fdt32_{ld,st}().
