[RFC] da850: DDR2/mDDR memory controller driver

[bgolaszewski@baylibre.com (Bartosz Golaszewski)]

This is a follow-up for the series[1] adding new bus and memory drivers
to better support the TI LCD controller on the da850-lcdk board.

The general consensus of the discussion that followed was that DT is
not the right tool for this kind of SoC performance tweaks.

In order to avoid committing to stable DT bindings, we only introduce
two common properties (compatible and reg) while the configuration
register values are hard-coded for each board (currently only lcdk).

I'm sending a single patch this time as RFC to get some reviews and
see it the approach is viewed as correct.
