This reverts commit 951f3512db
drm/i915: Do not handle backlight combination mode specially
since this commit introduced other regressions due to untouched LBPC
register, e.g. the backlight dimmed after resume.
In addition to the revert, this patch includes a fix for the original
issue (weird backlight levels) by removing the wrong bit shift for
computing the current backlight level.
Also, including typo fixes (lpbc -> lbpc).
