OMAP: WDT: Split OMAP1 and OMAP2PLUS device registration
This patch splits omap_init_wdt() into separate omap_init_wdt() functions under mach-omap1 and mach-omap2 and set them up with subsys_initcall. Also it uses omap_device_build() API instead of platform_device_register() for watchdog timer device registration for OMAP2plus chips. For OMAP2plus chips, the device specific data defined in centralized hwmod database will be used.
