dechao_gong 49f87935e5 arch/arm/rtl8721f: add RTC driver support
Wire the shared Ameba RTC driver (arch/arm/src/common/ameba/ameba_rtc.c)
into RTL8721F (amebagreen2).  The driver is chip-agnostic and reads only
per-chip macros from ameba_rtc_chip.h; RTL8721F differs from amebadplus
only in the RTC interrupt vector (RTL8721F_IRQ_RTC, vector 41).  The
APBPeriph_RTC masks and RTC_BASE_YEAR (1900) are identical across all
current Ameba chips.

 - ameba_rtc_chip.h: per-chip RTC IRQ / clock masks / base year
 - Make.defs, ameba_board.mk: compile ameba_rtc.c and the fwlib RAM
   RTC source when CONFIG_AMEBA_RTC=y
 - board: rtl8721f_rtc.c registers /dev/rtc0 from bringup
 - configs/rtc: examples/alarm profile
