Add ddrc memory controller node in dts. The size mentioned in dts is 0x30000, because we need to access DDR_QOS INTR registers located at 0xFD090208 from this driver.

Ok, talking to Mark on IRC, he says those DT changes normally go through
the arm-soc tree.
And I'm fine with that except if we do that, then the EDAC changes
go through my tree and those drivers could end up temporarily broken
depending on the merge order and timing.
So should we perhaps make an arm-soc shared, immutable branch which you
guys export for me with those DT changes applied, which I can merge into
my tree and apply the EDAC changes ontop.
This is what we've been doing with the tip tree until now and it has
proven successful.
Thoughts?
