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).

Changes in v2:
- remove the DEBUG (missed this initially, as there were no debug() calls in the file anyway)
- rework the reload_value code for improved readability
- pull the uc_priv->clock_rate init into the OF_PLATDATA block

Applied to u-boot-rockchip, thanks!
