Add the nodes for the MSTPRI configuration and DDR2/mDDR memory
controller drivers to da850.dtsi.

Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>

---
v1 -> v2:
- moved the priority controller node above the cfgchip node
- renamed added nodes to better reflect their purpose

Then the driver is too noisy and should be cleaned up.

IMO, what exactly are the error messages? Sounds like the driver is
being too verbose, and calling things errors that are not really errors.
