The MODEMR register offset changed on R8A779A0, make the MODEMR offset configurable. Fill the offset in on all clock drivers. No functional change. Based off "clk: renesas: Make CPG Reset MODEMR offset accessible from struct cpg_mssr_info" by Hai Pham <hai.pham.ud@renesas.com> Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
