[ARM] 4303/3: base kernel support for TI DaVinci Add base kernel support for the TI DaVinci platform. This patch only includes interrupts, timers, CPU identification, serial support and basic power and sleep controller init. More drivers to come.

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.
