From: Kazuya Mizuguchi <kazuya.mizuguchi...@renesas.com>
This patch updates the ravb binding to support the r8a7795 SoC by:
- Adding a compat string for the new hardware
- Adding 25 named interrupts to binding for the new SoC;
older SoCs continue to use a single multiplexed interrupt
The example is also updated to reflect the r8a7795 as this is the
more complex case.
Based on work by Kazuya Mizuguchi and others.

* First post; broken out of a driver update patch
* As discussed with Geert Uytterhoeven and Sergei Shtylyov
- Binding: Make all interrupts mandatory as named-interrupts of
the form ch%u
