9eeab57211 imx_watchdog: Do not assert WDOG_B on watchdog init 
Currently the driver asserts WDOG_B by clearing WCR_WDA bit when
enabling the watchdog. Do not clear WCR_WDA.

587c3f8ebe imx_watchdog: always set minimal timeout in reset_cpu 
The problem is that timeout bits in WCR register were leaved unchanged.
So previously set timeout value was applied and therefore 'reset'
command takes any value up to two minutes, depending on previous
watchdog settings, instead of minimal 0.5 seconds.

f532727d16 imx_watchdog: Add a header file for watchdog registers 
Create fsl_wdog.h to store the watchdog registers and bit fields.

This can be useful when accesses to the watchdog block are made from other
parts, such as arch/arm/ cpu code.
