[PATCH] ARM: dts: blanche: Add support for HSCIF0 on CN5

[Magnus Damm]

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

r8a7792 Blanche has depending on dip switch and jumper settings
either HSCIF0 or CAN0 exposed on the on-board CN5 connector.

This patch adds HSCIF0 to the Blanche dts as serial2.

Signed-off-by: Magnus Damm <damm+rene...@opensource.se>

 Currently the r8a7792 PFC is lacking support for HSCIF devices
 so the PFC driver needs to be updated to avoid error messages
 on the boot console.
