[PATCH v2] iommu/ipmmu-vmsa: Include SoC part number in DT binding docs

[PATCH v2] iommu/ipmmu-vmsa: Include SoC part number in DT binding docs

[Magnus Damm]

From: Magnus Damm <damm+renesas@opensource.se>

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@opensource.se>
---

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

 Thanks to Laurent for feedback!
