Watchdog device controller found on all modern SoCs from i.MX series
and firstly introduced in i.MX25 is not one in one compatible with the
watchdog controllers on i.MX21, i.MX27 and i.MX31, the latter
controlles don't have WICR (and pretimeout notification support) and
WMCR registers. To get benefit from the more advanced watchdog device
and to avoid operations over non-existing registers on legacy SoCs add
fsl,imx25-wdt compatible to descriptions of all i.MX25 compatible
watchdog controllers.
