Wire the RTL8720F into the shared Ameba watchdog driver (arch/arm/src/common/ameba/ameba_wdg.c), registered as /dev/watchdog0. Only the per-chip base address and IRQ differ, so this adds a small ameba_wdg_chip.h (WDG2 non-secure system watchdog at 0x40801D80, KM4TZ_NS_WDG IRQ 52, verified against the SoC hal_platform.h and ameba_vector_table.h) plus the Make.defs/CMakeLists build hooks, the board bring-up registration, and a wdg defconfig. The shared driver is unchanged. Also corrects the RTL8720F row in the rtl8721dx chip-header reference table (the non-secure system WDG IRQ is KM4TZ_NS_WDG = 52).
