Add a device node for the Product Register, which provides SoC product
and revision information.

PRR node is added as part of upstream commit eb4cdda7a30b3 ("ARM: dts:
r8a7742: Initial SoC device tree") as this commit includes initial SoC
DTSI PRR node cannot be individually backported hence this new commit.
