Davinci: watchdog reset separation across socs
The earlier watchdog reset mechanism had a couple of limitations. First, it
embedded a reference to "davinci_wdt_device" inside common code. This
forced all derived platforms (da8xx and tnetv107x) to define such a device.
This also would have caused problems in including multiple socs in a single
build due to symbol redefinition.
With this patch, davinci_watchdog_reset() now takes the platform device as an
argument. The davinci_soc_info struct has been extended to include a reset
function and a watchdog platform_device. arch_reset() then uses these
elements to reset the system in a SoC specific fashion.
