Add a sec DTS node and reference RCU and SEC via adi,rcu/adi,sec phandles, reducing the watchdog reg to only its own registers. Add "syscon" to the compatible of RCU and SEC nodes so that syscon_regmap_lookup_by_phandle() can resolve them. The driver uses syscon_regmap_lookup_by_phandle() for RCU and SEC, and regmap_init_mem() for WDT, replacing all iowrite32/ioread32 calls with regmap_write/regmap_read. This aligns the DTS layout with Linux. Signed-off-by: Jie Zhang <jie.zhang@analog.com>
