watchdog: aspeed: Move init to arch_initcall
Probing at device_initcall time lead to perverse cases where the watchdog was probed after, say, I2C devices, which then leaves a potentially running watchdog at the mercy of I2C device behaviour and bus conditions. Load the watchdog driver early to ensure that the kernel is patting it well before initialising peripherals.
