[PATCH] arm64: dts: draak: Add serial console pins

[Geert Uytterhoeven]

Add pin control for SCIF2.

Signed-off-by: Geert Uytterhoeven <geert+rene...@glider.be>
---
To be applied after v4.14-rc1, when commit 794a6711764658a1 ("pinctrl:
sh-pfc: Initial R8A77995 PFC support") has hit mainline.

Else the serial console will fail, reporting (on earlycon):

    sh-sci e6e88000.serial: could not find pctldev for node 
/soc/pin-controller@e6060000/scif2, deferring probe
