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.
