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] BUG=None BRANCH=None TEST=None Change-Id: I006614026143fa180702ac0d1cc2ceb1b3c6eeb0 Signed-off-by: Gwendal Grignou <gwendal@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/1518660 Reviewed-by: Daisuke Nojiri <dnojiri@chromium.org>
