arm: rmobile: rcar: Move arch_preboot_os function to rcar-gen2-common/common.c
The arch_preboot_os function used in boards using R-Car ARM SoC (r8a7790,
r8a7791, r8a7793 and r8a7794) is common.
This makes rcar-gen2-common/common.c file providing common function for
R-Car ARM SoC, and moves this function to this file.
