[PATCH v2] ARM: dts: imx: Always enable the watchdog

From: festevam@gmail.com (Fabio Estevam)
Date: 2012-07-28 19:43:30 

From: Fabio Estevam <redacted>

Instead of enabling the watchdog in each individual dts file, select in 
the SoC dtsi file instead.

Changes since v1:
- Remove the wdog setting in imx27-phytec-phycore.dts

"okay" is generally used by <board>.dts to overwrite "disabled" set in
<soc>.dtsi.  If we want to have the block enabled in <soc>.dtsi, simply
do not leave status property there, and "okay" will be the default.
