dm: core: Add dev_get_addr_size_index() to retrieve addr and size
The currently available functions accessing the 'reg' property of a
device only retrieve the address. Sometimes its also necessary to
retrieve the size described by the 'reg' property. This patch adds
the new function dev_get_addr_size_index() which retrieves both,
the address and the size described by the 'reg' property.
