C8051F120初始化SPI，启动CC2420。通过将CC2420 得VREG_EN 引脚置位高电平使能Voltage regulator，等待其稳定；然后重新启动CC2420 芯片，等待晶振起振。-Initialize SPI, start the CC2420. By CC2420 have VREG_EN pin high to enable the set Voltage regulator, waiting for their stability and then re-start the CC2420 chip, since waiting for crystal oscillator.
