From: Magnus Damm <damm+renesas@xxxxxxxxxxxxx>
Add part numbers for APE6 and current set of R-Car Gen2 SoCs to the
IPMMU DT binding documentation. The example is also updated to show
how the generic compatible string may be used as fallback.
Signed-off-by: Magnus Damm <damm+renesas@xxxxxxxxxxxxx>

Changes since V1:
- Updated compat string section to the following:
"Must contain SoC-specific and generic entries from below."
Thanks to Laurent for feedback!
