If this removal is intentional, we can get rid of the redundant call to
fdtdec_get_addr_size_auto_parent above since the locals 'addr' and 'size' are no
longer used.

You could just do return fdt_setprop(...) here instead. And a similar cleanup
can be done for fdtdec_add_reserved_memory below, if you wanna take it up in the
next revision.
