On R-Car H3, on-chip peripheral modules that can make use of DMA are
wired to either SYS-DMAC0 only, or to both SYS-DMAC1 and SYS-DMAC2.
Add the missing DMA properties pointing to SYS-DMAC2 for HSCIF[0-2],
SCIF[0125], and I2C[0-2]. These were initially left out because early
firmware versions prohibited using SYS-DMAC2. This restriction has been
lifted in IPL and Secure Monitor Rev1.0.6 (released on Feb 25, 2016).

FTR, other devices already have dmas pointing to SYS-DMAC2.
v2:
- Add Reviewed-by,
- Update forgotten SCIF2 node.
