1eb0a464b7 aspeed: Watchdog Timer Driver 
This driver supports ast2500 and ast2400 SoCs.
Only ast2500 supports reset_mask and thus the option of resettting
individual peripherals using WDT.

0753bc2d30 dm: Simple Watchdog uclass 
This is a simple uclass for Watchdog Timers. It has four operations:
start, restart, reset, stop. Drivers must implement start, restart and
stop operations, while implementing reset is optional: It's default
implementation expires watchdog timer in one clock tick.

253531bbd9 wdog: Add the watchdog driver for MX7ULP. 
This driver implements the HW WATCHDOG functions. Which needs
to set CONFIG_HW_WATCHDOG to use them. This is disabled by default for
mx7ulp.

Use watchdog for reset cpu. Implement this in the driver.
Need to define CONFIG_ULP_WATCHDOG to build it.
