[PATCH 2/3] arm64: dts: r8a7795: Add CAN support

[Simon Horman]

From: Ramesh Shanmugasundaram <ramesh.shanmugasundaram at bp.renesas.com>

Adds CAN controller nodes for r8a7795.

Note: CAN channel register base address mentioned in R-Car Gen3 Hardware
User Manual v0.5E is incorrect. The corrected base addresses are:

CAN Channel 0 - 0xe6c30000
CAN Channel 1 - 0xe6c38000
