dm: core: Add dev_read_resource() to read device resources Add a function which reads resources from a device, such as the device hardware address. This uses the "reg" property in the device. Unlike other functions there is little sense in inlining this when livetree is not being used because it has some logic in it and this would just bloat the code size.

dm: core: Add ofnode_read_resource() We sometimes need to read a resource from an arbitrary node. In any case for consistency we should not put the live-tree switching code in a dev_read_...() function. Update this to suit.
