wdt: Add Aspeed watchdog device model
The Aspeed SoC includes a set of watchdog timers using 32-bit
decrement counters, which can be based either on the APB clock or
a 1 MHz clock.
The watchdog timer is designed to prevent system deadlock and, in
general, it should be restarted before timeout. When a timeout occurs,
different types of signals can be generated, ARM reset, SOC reset,
System reset, CPU Interrupt, external signal or boot from alternate
block. The current model only performs the system reset function as
this is used by U-Boot and Linux.
