Wire the RTL8720F into the shared Ameba timer driver (arch/arm/src/common/ameba/ameba_timer.c), registered at /dev/timer0 (TIM1) and /dev/timer1 (TIM2). Only the per-chip base addresses, RCC masks and IRQs differ, so this adds a small ameba_timer_chip.h (the two 32-bit basic LTIM timers at 0x40808200 / 0x40808400, 32.768 kHz, APBPeriph_LTIM1/2, IRQ_TIMER1/2, verified against the SoC hal_platform.h / sysreg_lsys.h / vector table) plus the Make.defs/CMakeLists build hooks, the fwlib ram_common/ameba_tim.c RAM source (now also pulled in by CONFIG_AMEBA_TIMER, matching the PWM rule), the board bring-up registration and a timer defconfig. The shared driver is unchanged. TIM0 is left untouched because the boot ROM claims it as the always-on system timer; reprogramming it would break every SDK delay.
