[U-Boot] [U-Boot, v2, 3/6] rockchip: timer: add device-model timer driver for RK3368 (and similar)

[Philipp Tomsich]

> 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).

Applied to u-boot-rockchip, thanks!
