Changes since V10 (Simon Horman <horms+renesas@verge.net.au>)
- As suggested by Geert Uyterhoven
  + R8A7795_CLK_SCIF2  is 310 not 210

Changes since V9: (Magnus Damm <damm+renesas@opensource.se>)
- Added SCIF2 DMA bits again
- Converted DT nodes for MSTP to MSSR, adjusted r8a7795-clock.h
- Include clock-output-names

Changes since V8: (Magnus Damm <damm+renesas@opensource.se>)
- Dropped SCIF2 DMA bits - thanks Laurent!
- Changed name of mstp2 and mstp3 nodes - thanks Geert!
- Added Acked-by from Laurent

Changes since V7: (Magnus Damm <damm+renesas@opensource.se>)
- Folded together above SCIF2 patches
- Added SCIF2 DMA bits
- Got rid of clock-output-names
- Replaced renesas,clock-indices with clock-indices

Based on:
 [PATCH 9/25] arm64: renesas: r8a7795: Add SCIF2 support
 [PATCH 1/6] arm64: renesas: r8a7795 dtsi: Mark scif2 disabled
 [PATCH 3/6] arm64: renesas: r8a7795 dtsi: Add all SCIF nodes
