common: bit change 1 << constants with BIT(constants)
Mechanical replacement of bit operation where operand is a constant.
More bit operation exist, but prone to errors.
Reveal a bug in npcx:
chip/npcx/system-npcx7.c:114:54: error: conversion from 'long unsigned int' to 'uint8_t' {aka 'volatile unsigned char'} changes value from '16777215' to '255' [-Werror=overflow]
