drm/i915: Revive combination mode for backlight control
This reverts commit 951f3512dba5bd44cda3e5ee22b4b522e4bb09fb
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).
