Add DT overlay to bind RPi Display 2, both 5" and 7" variant, on
Retronix R-Car V4H Sparrow Hawk board. All of display output, the
touch controller, and backlight control have been tested.

V2: Build also the plain DTBO for each DTO. Each new DTO entry in the
    Makefile has three lines, the DTBO, combined and DTB targets. This
    is easy to miss, so note this down for myself.

make dtbs_check:

    arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk-rpi-display-2-5in.dtb:
gpio@45 (raspberrypi,touchscreen-panel-regulator-v2): '#gpio-cells',
'#pwm-cells', 'gpio-controller' do not match any of the regexes:
'^pinctrl-[0-9]+$'
            from schema $id:
http://devicetree.org/schemas/regulator/raspberrypi,7inch-touchscreen-panel-regulator.yaml#

I noticed you posted patches to fix all other issues in DT bindings
triggered by this series, so I assume you just forgot to post the
fixes for this one (which you authored ;-)?

I think the following patch handles this:
