It's quite likely that this does not have to be a fixed mapping
any more. Just have a look at how drivers/clocksource/dw_apb_timer_of.c
calls of_iomap() to get the address.

Yes, this is already on my list of plans.  The in-tree TTC driver
unfortunately doesn't yet support device tree bindings.  Are you
comfortable waiting on the DT-ification of the TTC in a follow-up
patchset?

Yes, that's fine. If you do that, you can also move the driver to
drivers/clocksource in another patch.
