DA9055_WATCHDOG (introduced in v3.8) needs to select WATCHDOG_CORE so that it will
build cleanly.  Fixes these build errors:

da9055_wdt.c:(.text+0xe9bc7): undefined reference to `watchdog_unregister_device'
da9055_wdt.c:(.text+0xe9f4b): undefined reference to `watchdog_register_device'

Convert omap_wdt to new watchdog core. On OMAP boards, there are usually
multiple watchdogs. Since the new watchdog core supports multiple
watchdogs, all watchdog drivers used on OMAP should be converted.

The legacy watchdog device node is still created, so this should not
break existing users.

With device tree support in place, we should not use IMX_HAVE_PLATFORM_IMX2_WDT
as a dependency for selecting the imx2_wdt driver.

Use ARCH_MXC symbol instead, so that the driver can be even selected by a device-tree
only SoC, such as i.MX6.

I think this should be sent to upstream via samsung tree because
