The datasheet states that most of the configuration should be set in the
control register in the first place, before actually enabling the
hardware. So far only half of the configuration was made in the first
step, which does not make really sense and would complicating the code
when introducing support for the am437x hardware.

Let's move that register write a bit below to enclose more configuration.
