Add optional host top register base for the reg binding description.
Is this based a on a new version of the IP? Shall we make the second reg
mandatory for the new HW? If I remember correctly the reg needs to be restored
after power save event. So I suppose mmc won't work if that's not done. So
optional wouldn't be the right approach.
Can you please clarify if that's the case.
Thanks,
Matthias
