drm/i915/dpcd_bl: Remove redundant AUX backlight frequency calculations
Noticed this while moving all of the VESA backlight code in i915 over to
DRM helpers: it would appear that we calculate the frequency value we want
to write to DP_EDP_BACKLIGHT_FREQ_SET twice even though this value never
actually changes during runtime. So, let's simplify things by just caching
this value in intel_panel.backlight, and re-writing it as-needed.
Changes since v1:
* Wrap panel->backlight.edp.vesa.pwm_freq_pre_divider in
DP_EDP_BACKLIGHT_FREQ_AUX_SET_CAP check - Jani
