Hi!

From: Geert Uytterhoeven <geert+renesas@...>

commit f3c6c120614cfb02827ee7bbe6c4240847cc5f12 upstream.

The R-Car PCIe controller does not use interrupts when configured
for endpoint mode, hence the bindings do not document the interrupts
property. However, all DTS files provide interrupts properties, and
thus fail to validate.

Fix this by documenting the interrupts property.

Looks good to me. I can apply it to 4.19-cip if there are no other
comments.

Best regards,
Pavel
