Subject: [PATCH 1152/1795] clk: renesas: rcar-gen3: Always use
 readl()/writel()

The R-Car Gen3 CPG/MSSR driver (again) uses a mix of
clk_readl()/clk_writel() and readl()/writel() to access the clock
registers. Settle on the generic readl()/writel().

Cfr. commit 30ad3cf00e94f4a7 ("clk: renesas: rcar-gen3-cpg: Always use
readl()/writel()").
