dechao_gong a85db6d28f arch/arm/rtl8721f: bring up minimal NSH (P1) 
Wire the RTL8721F km4tz core up to a working NuttShell:

- irq.h: renumber the KM4TZ external vector table to the RTL8721F
  APIRQn map (UART_LOG=24, IPC=5, +GPIOB/C, TIMER7/8, ...).
- ameba_loguart.c: fix the LOG-UART base to 0x40810000.  The former
  0x401C6000 belongs to a different Ameba part; the wrong base bus-
  faulted on the RX interrupt-enable write while TX still worked
  (LOGUART_PutChar uses its own ROM-internal base).
- ameba_app_start.c: adjust the MPU read-only / RAM regions for the
  RTL8721F memory map and seed the RTC on first power-on so the
  SDM32K-clocked SYSTIMER comes up (mirrors the SDK app_rtc_init).
- ameba_ipc.c: move the km4tz<->km4ns IPC to APIRQn 5 (IPC_CPU0).
- ameba_board.mk: pull in fwlib ameba_rtc.c for the RTC_* symbols.
- defconfig: RTL8721F RAM map, enable TIMER/TIMER_ARCH/ARMV8M_SYSTICK
  for a live system tick, and drop the WiFi/NET stack for now.
- scripts/Make.defs: use the RTL8721F_NOR flash profile.

Boots cleanly to nsh> on hardware; tick, RX and builtin apps verified.
