Merge tag 'renesas-arm64-dt-for-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/late

Pull "Renesas ARM64 Based SoC DT Updates for v4.9" from Simon Horman:

Clean up:
* Remove unnecessary cap-mmc-highspeed property from SDHI nodes on r8a7795 SoC
* Add SoC-specific compatible property to audio-dmac nodes on r8a7795 SoC

New Board:
* Add r8a7794/h3ulcb board

Enablement:
* Add PFC and GPIO to r8a7796 SoC
* Enable DU and USB 2.0 on r8a7795/salvator-x board
* Add VTP, FCPV, FCPF and FDP1 to r8a7795 SoC
* Set maximum frequency for SDHI clocks on r8a7795 SoC
