Merge "DTS changes for X-Gene platforms queued for v4.5" from Duc Dang

This patch set adds DTS entries to support various IPs
for X-Gene v1 and X-Gene v2 SoC:
- X-Gene v1: Enable support for MMC, USB, GPIO controllers,
  I2C controller, L2 Cache topology
- X-Gene v2: Enable support for MMC, USB, GPIO controller,
  I2C controller (with RTC), PCIe controller with GICv2m MSI,
  EDAC, L2 Cache topology, TRNG
