I think we can do without it: there are only three machines that have dt files with a reg-offset property in their uart:
- nds32 ae3xx was added in 4.17 and requires it there - powerpc (virtex) has its own early console support and doesn't rely on earlycon.c - mips (nexys4ddr) could use it, but has never made use of the earlycon driver in its DT files. It should now work out of the box in 4.17
