Because we need to access the reset controller at the time the timer
is probed, which is way before the device model is initilized, and the
"real" reset controller driver is probed.
I'm not really fond of the solution either, but there's no other
solution, if we set aside "rework the driver / device model so that it
initializes properly".

Then you cannot use the HS timer.
