[PATCH] ARM: rmobile: beacon-renesom: Enable QSPI NOR Flash

There is a QSPI NOR flash part on the board. Because this chip isn't
yet supported in Linux, but it is supported in U-Boot, and the
face that the RPC_SPI compatible names are different in U-Boot and
Linux, the device tree updates are confined to -u-boot.dtsi files.
