dm: core: Add option to configure an offset for the address translation

Some platforms need to ability to configure an offset to the standard
addresses extracted from the device-tree. This patch allows this by
adding a function to DM to configure this offset (if needed).

BOOTP broadcast 2
BOOTP broadcast 3
BOOTP broadcast 4

This commit does not have an issue in itself, but it revelead a problem
with the Ethernet initialization.

As per the AR8035 datasheet:

"For a reliable power on reset, suggest to keep asserting the reset
low long enough (10ms) to ensure the clock is stable and clock-to-reset
1ms requirement is satisfied."

So do as suggested and keep the reset low for 10ms.

Also add a 100us delay after deasserting the reset line
to guarantee that the PHY ID can be read correctly and the Atheros

Enables use of this function as default, but after this it's not
possible to get dev address for the case in which: '#size-cells == 0'

This causes errors when getting address for some GPIOs, for which

since:
commit: f05ad9ba "Add a way to skip relocation"

tqm5200s board fails to boot. Reason is that
board_init_f has a function parameter bootflag,
which is not setup in
in arch/powerpc/cpu/mpc5xxx/start.S _start

So board_init_f gets a undefined bootflag,
currently the gd pointer address. Unfortunately
this address sets the GD_FLG_SKIP_RELOC bit,
so u-boot code gets not relocated and u-boot
does not boot ...

Init bootflag with 0, and tqm5200 boots fine again.
