dm: core: ofnode: Add ofnode_read_bootscript_flash()
ofnode_read_bootscript_flash() reads bootscript address from
/options/u-boot DT node. bootscr-flash-offset and bootscr-flash-size
properties are read and values are filled. When bootscr-flash-size is not
defined, bootscr-flash-offset property is unusable that's why cleaned.
Both of these properties should be defined to function properly.
Also add test to cover this new function.
