dm: core: ofnode: Add ofnode_read_bootscript_address()
ofnode_read_bootscript_address() reads bootscript address from
/options/u-boot DT node. bootscr-address or bootscr-ram-offset properties
are read and values are filled. bootscr-address has higher priority than
bootscr-ram-offset and the only one should be described in DT.
Also add test to cover this new function.
