[U-Boot] [PATCH v3 1/2] imx_watchdog: Add a header file for watchdog registers

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

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.
