[PATCH v4 8/9] arm64: dts: renesas: r9a09g057h44-rzv2h-evk: Enable OSTM, I2C, and SDHI

[Prabhakar <prabhakar.csengg@xxxxxxxxx>]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Enable OSTM0-OSTM7, RIIC{0,1,2,3,6,7,8}, and SDHI1 (available on the SD2
connector) on the RZ/V2H EVK platform.

Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>
