v2018.01 commit e23eb942ad103f ("ARM: rmobile: Stop using rcar-common/common.c on Gen3") removed board/renesas/rcar-common/common.c from the build chain. The reasoning is that calling arch_preboot_os() is no more needed.
However, we use this file as a place for R-Car common features / functionalities, shared by both Renesas reference targets and any custom R-Car boards. Without such file, we have to duplicate lots of code into board-specific *.c files.
Restore rcar-common/common.c and zap the unneeded arch_preboot_os(). No functional change intended.

This should be a separate patch, one which only removes this code which is unused. Presumably the whole file should just be removed.

This ends up including an empty file, which is useless.
