[U-Boot] [PATCH 1/2] core: ofnode: Fix ofnode_get_addr_size_index function
Currently the else part of ofnode_get_addr_size_index function does not fetch addresses based on the index but rather just returns the base address. Fix that.

Add ofnode_get_addr_size_index function to fetch the address and size of the reg space based on index.
