iommu/ipmmu-vmsa: Hook up r8a779(70|95) DT matching code
Support the r8a77970 (R-Car V3M) and r8a77995 (R-Car D3) IPMMUs by sharing feature flags with r8a7795 (R-Car H3) and r8a7796 (R-Car M3-W). Also update IOMMU_OF_DECLARE to hook up the compat strings. Based on work for the r8a7796 by Magnus Damm [rebased on v4.17] Signed-off-by: Jacopo Mondi <jacopo+renesas@jmondi.org> Signed-off-by: Simon Horman <horms+renesas@verge.net.au> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Joerg Roedel <jroedel@suse.de>
