Pull watchdog updates from Wim Van Sebroeck:
"This contains:
- new driver for ST's LPC Watchdog
- new driver for Conexant Digicolor CX92755 SoC
- new driver for DA9062 watchdog
- Addition of the watchdog registration deferral mechanism
- several improvements on omap_wdt
- several improvements and reboot-support for imgpdc_wdt
- max63xx_wdt improvements
- imx2_wdt improvements
- dw_wdt improvements
- and other small improvements and fixes"
