With dtoc emitting fdt64_t for addresses (and region sizes), the array
indices for accessing the reg[] array needs to be adjusted. This
adjusts the Rockchip DM timer driver to correctly handle OF_PLATDATA
given this new structure layout.

(cherry picked from commit 6675c952f20b7b3cfedd57c9c49305289a89403c)
To make the Rockchip DM timer driver useful for the timing of
bootstages, we need a few enhancements:
- This implements timer_get_boot_us.
- This avoids reinitialising the timer, if it has already been
set up (e.g. by our TPL and SPL stages). Now, we have a single
timebase ticking from TPL through the full U-Boot.
- This adds support for reading the timer even before the
device-model is ready: we find the timer via /chosen/tick-timer,
then read its address and clock-frequency, and finally read the
timeval directly).

When I originally added this driver, I did some careless (and in
retrospect: mindless) copy & paste for the U_BOOT_DRIVER structure
skeletion... unfortunately, the 'arc_timer' string was committed
and slipped through all reviews.
This fixes the U_BOOT_DRIVER name to read 'rockchip_rk3368_timer'
(as originally intended).

This adds a device-model driver for the timer block in the RK3368 (and
similar devices that share the same timer block, such as the RK3288) for
the down-counting (i.e. non-secure) timers.
This allows us to configure U-Boot for the RK3368 in such a way that
we can run with the secure timer inaccessible or uninitialised (note
that the ARMv8 generic timer does not count, if the secure timer is
not enabled).
