Add support for External Memory Controller found in Tegra 4 SoC along
with adjustments required for it to work properly.

Tested on ASUS TF701T (T40X) and Nvidia Tegratab (T40S). Both work fine.

---
Changes in v2:
- fix programming completion detection (changed EMC reg to MC reg reading)
- Tegra114 incorporated into Tegra124 dt-bindings schema

Changes in v3:
- adjusted MC and EMC schema to move description and ref into common property
- added Tegra114 support into devfreq driver
- added MC/EMC to DC interconnections
