drm/i915/backlight: setup backlight pwm alternate increment on backlight enable
Backlight enable is supposed to do a full setup of the backlight. We
were missing the PWM alternate increment bit in the south chicken
registers on lpt+ pch. This potentially caused a PWM frequency change
when the chicken register value was lost e.g. on suspend.
v2 by Jani, rebase on the patch caching alt increment
