Add the nodes for the MSTPRI configuration and DDR2/mDDR memory

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

Hi David,
I did that initially[1][2] and it was rejected by Kevin[3] and Laurent[4].
FYI this patch has already been queued by Sekhar.
Thanks. I did not see those threads.
FYI to maintainers, having these enabled by default causes error
messages in the kernel log for other boards that are not supported by
the drivers.
Then the driver is too noisy and should be cleaned up.
Since there is only one board that is supported and soon
to be 2 that are not, I would rather have this disabled by default to
avoid the error messages.
IMO, what exactly are the error messages? Sounds like the driver is
being too verbose, and calling things errors that are not really errors.
It is just one line per driver.
dev_err(dev, "no master priorities defined for this board\n");
and
dev_err(dev, "no settings defined for this board\n");
Since "ti,da850-lcdk" is the only board supported in these drivers, all
other boards will see these error messages.
Also, these modules will be loaded and taking up memory on boards that
don't use them. This not really a big deal and they can be explicitly
disabled, so maybe it was not worth mentioning.
Kevin
