[v2,00/14] treewide: Initial support for R-Car S4-8

This patch series adds initial support for the Renesas R-Car S4-8
(r8a779f0) SoC.

Changes from v1:
 - Remove some merged patches by Geert-san. (Thanks!)
 - Fix dt-binding doc of Spider boards
 - Fix r8a779f0 SYSC / Clock definitions
 - Fix dt-binding doc of scif for R-Car Gen4
 - Fix ordering in Kconfig of drivers/soc/renesas/Kconfig
 - Remove .reg in renesas-soc.c for rcar_gen4.
 - Remove moditication of V3U_WDTRSTCR.
 - Split R-Car Gen4 support at first for SYSC and CPG driver.
 - Fix some minor issues in r8a779f0-cpg-mssr.c.
 - Use DEF_BASE for .sdsrc.
 - Rebase the latest renesas-clk for cpg_sd_clk_register().
