Since we have a SoC level node we should make use of it and have
all nodes which are within the SoC, inside that node. This also
saves an extra interrupt-parent properties. While at it, also
order the Coresight nodes according to register addresses.

Hi Shawn,
Not sure if there was a reasoning behind having all these nodes
not within the soc subnode, but it seems to me somewhat uncommon
in the i.MX world...
If possible this patchset should go into v4.8 since 2/2 is a fix,
however, I understand that 1/2 is not really post rc1 material...
What do you think?
