When restarting a CPU powered by the PCA9450 power management IC, it is beneficial to use the PCA9450 to power cycle the CPU and all its connected peripherals to start up in a known state. The PCA9450 features a cold start procedure initiated by an I2C command. Add a restart handler so that the PCA9450 is used to restart the CPU. The restart handler sends command 0x14 to the SW_RST register, initiating a cold reset (Power recycle all regulators except LDO1, LDO2 and CLK_32K_OUT) As the PCA9450 is a PMIC specific for the i.MX8M family CPU, the restart handler priority is set just slightly higher than imx2_wdt and the PSCI restart handler. This makes sure this restart handler takes precedence.
