Merge "Fixes for X-Gene DTS for v4.5" from Duc Dang:

This patch set fixes the node names of X-Gene I2C, GPIO
controller DT nodes; and also removes I2C clock nodes as
the same clock is shared between 2 I2C controllers
on X-Gene SoC.

  arm64: dts: X-Gene v2: I2C1 clock is always on
  arm64: dts: X-Gene v1: I2C0 clock is always on
  arm64: dts: Fix to use standard DT node names for X-Gene 1 and X-Gene 2 platforms
