Subject: [PATCH] drivers: core: Add translation in live tree case

The function dev_read_addr calls ofnode_get_addr_index in the live tree
case, which does not apply bus translations to the address read from the
device tree. This results in illegal addresses on boards that rely on
bus translations being applied.

Fix this situation by applying bus translations in the live tree case as
well.
