[U-Boot] [PATCH v2 1/7] arm: rmobile: rcar: Move module control register to header file of SoC

Module control registers of R-Car ARM SoC (r8a7790, r8a7791, r8a7793 and r8a7794) are same address. This moves these to header file of SoC.

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.

The infomation of module control register for R-Car ARM SoC (r8a7790, r8a7791, r8a7793 and r8a7794) are almost the same, they can be combined into one structure. This provides structure that summarizes infomation of module control register and default register values. And this structure is the module control use of the kernel at boot time.

This stops clock except INTC-RT, MSIF, INTC-SYS, IRQC and SCIF before kernel boots.
