dm: core: add support for getting register address and size
Current dev_read_*() API lacks support to get address and size
of a "reg" property by name or index. Add support for the same.
Livetree support has been added but not tested on real hardware.
The existing unit tests testing reading address from device-tree
have been updated to test address as well as size.
