[0/3] Support reading an u32 from a multi-value property

The main part of the series consists of adding the dev_read_u32_index
and dev_read_u32_index_default functions. During implementation and
testing I noticed the lack of testing for the 64-bit data access
functions.
I decided to add the 64-bit test patch to the series to avoid merge
conflicts that could have occurred with the submission of a single
separated patch. In fact, it also contains changes to the
test/dm/test-fdt.c file.

If this series is accepted, it will be possible to evaluate the
addition of functions for indexed access also for the dev_read_s32 and
dev_read_u32u functions. Maybe to add in a second version of this
series.
