This series introduces the EMC clock scaling support for Tegra210. The
new version has a significant change, which drops the EMC table bindings
and replaces by memory region node of EMC table.
And most of the comments in V1 have been addressed.
Thanks.
v4:
* make sure the behavior is compatible with the case if the kernel uses
the older DTB which doesn't have EMC node.
* remove the EMC clock statistic data in EMC debug fs.
