fdt: allow fdtdec_get_addr_size_*() to translate addresses
Some code may want to read reg values from DT, but from nodes that aren't
associated with DM devices, so using dev_get_addr_index() isn't
appropriate. In this case, fdtdec_get_addr_size_*() are the functions to
use. However, "translation" (via the chain of ranges properties in parent
nodes) may still be desirable. Add a function parameter to request that,
and implement it. Update all call sites to default to the original
behaviour.
