[PATCH] arm64: dts: r8a7795: update PFC node name to pin-controller

[Simon Horman]

The device trees for Renesas SoCs use either pfc or pin-controller
as the node name for the PFC device. This patch is intended to take a step
towards unifying the node name used as pin-controller which appears to
be more the more generic of the two and thus more in keeping with the DT
specs.

My analysis is that this is a user-visible change to the extent that kernel
logs, and sysfs entries change from e6060000.pfc and pfc at e6060000 to
e6060000.pin-controller and pin-controller at e6060000.
