Merge tag 'renesas-dt-for-v3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/dt

From Simon Horman:
Renesas ARM-based SoC DT updates for v3.12

* Reference implementation for kzm9d board
* Add MMCIF and SDHI DT templates for r8a7790 and r8a73a4 SoCs
* Use DT for SMP and GIC initialisation on emev2 SoC and kzm9d board
* Add GIO to dtsi of emev2 SoC
* Update dts command line of kzm9d board
* Add CPUFreq support to ape6evm board
* Add I2C controller DT nodes to r8a73a4 SoC
