In this CL, we add selecting LFCLK sources functionality for npcx7 ec series. (Please notice not all of npcx7 ec series support this feature.) Beside internal LFCLK source, ec also can choose the external 32kHz crystal oscillator as LFCLK source for the specific application. We also introduce a new definition, CONFIG_CLOCK_SRC_EXTERNAL, to switch this feature in the board level driver. This CL also adds: 1. LFCG register definitions in registers.h. 2. Change the order of each npcx modules by memory address. BRANCH=none BUG=none TEST=Output LFCLK source through GPIO75. Compare with external 32kHz crystal osc. on npcx7_evb and make sure the sources are the same.
